Things learned: 1. map method is used when we want transformation of whole array. 2. filter is used when we want to filter the arrar to obtain required value. 3. reduce is used when we want to reduce the array to single value eg (max, min, avg, sum, difference etc). 4. reduce passes two arguments one function(which includes accumulator and initial value as argument itself) and another initial value of accumulator. 5. Homework: const output = user.reduce(function(acc, curr){ if (curr.age < 30){ acc.push(curr.firstName); } return acc; }, [ ]) console.log(output);
@@lakshyapant5225 Kyuki accumulator(acc) ki pehli condition me hi aapne return kar diya. Vo function se exit ho jaayega, aage ka process ruk gaya pura.
Here is my solution: const output = users.reduce(function(acc, curr){ if(curr.age < 30){ acc.push(curr.firstName); //if age of current user is < 30, push there firstName into the acc array } return acc; }, [ ]); //initially, the acc will be an empty array console.log(output); Thanks Akshay for such a crystal clear explanation!!

11:49 Found the answer for why reduce is named so. According to an article on digital ocean - "A reducer will only return one value and one value only hence the name reduce." In simple terms, it reduces the array to a single value.
dude, you are a legend. I never saw anyone who explain a program the way you do. not just telling if you do this, this will happen, instead showing how it is happening.

Hi, @@debo01 No, this will not work because you initialized the reduce function with object literals {}. Since we are pushing (.push) the results we should use an array for initialization, just like @Mohammad Noushad Siddiqui did. Thanks.

11:50 - Name reduce was assigned with a purpose to maintain similarity between languages. We have similar reduce (and map, filter as well) in other languages also - Java, Python, Scala, Ruby etc. So having a consistent naming convention will be very easy for developers to get up and running when they switch from one language to another!

I know I'm already late for this but I have finally completed this JS tutorial today. It's just amazing and I don't have any words to describe and YES along with falling in love with JS, I fell in love with Akshay too 😊
I regret for not finding your channel earlier :( still neva too late :) . So much clarity and that eager to make viewers understand the topic. Hats off. Thanks a lot.
We can do something like this to get the desired output! const filterByAge = users.reduce((acc,item)=>{ if(item.age>30){ acc.push(item.firstName); } return acc },[])
I am addicted to the way you teach and changed the way, I used to learn. Now, I always hunt the blogs which go in-depth. Here is my H/W // find people whose age is less than 30 using reduce const users = [ {firstName: "Inderpreet", lastname:"singh", age:31}, {firstName: "Rahul", lastname:"Kumar", age:28}, {firstName: "Akshay", lastname:"Saini", age:20} ]; const output = users.reduce(function(acc, curr) { if(curr.age

wow you are the only man that express map,filter and reduce in simple way God blase you
Loved this JS series... The way you cover each topic is awesome... Easy to understand and remain forever. Thank you ❤️
I've watched many tutorials on this topic, but this one is truly the best!
// Code for the challenge given at 36:05
const outputlist = users.reduce((names, user) => {
if(user.age < 30){
names.push(user.firstname); //can also use names.unlist(user.firstname);
}
return names;
}, []);
can you please explain why you use [] instead of empty object {}
@@ShrikantKunte Thanks
because in the final output we need an array of first names of users whose age is less than 30
@@vidushikagupta2900
I also did the same broh
This works...
const reducedArray = users.reduce(function (acc, curr) {
if (curr.age < 30) {
acc.push(curr.first)
}
return acc
}, [])
Thanks Akshay for this series! You are a gem
curr.firstName :)
Superb explanation
console.log(final) ;
const array = users.reduce( function(arr , user){
if(user.age < 30){
arr.push(user.firstName) ;
}
return arr ;
} , [] ) ;
console.log(array) ;
Thanks for this amazing video.
I know I'm already late for this but I have finally completed this JS tutorial today. It's just amazing and I don't have any words to describe and YES along with falling in love with JS, I fell in love with Akshay too 😊
same😇🤩☺
You made this sooo simple to understand!! The reason why this playlist is soooooooo popular! Keep posting great contents.
I regret for not finding your channel earlier :( still neva too late :) . So much clarity and that eager to make viewers understand the topic. Hats off. Thanks a lot.
Here is my Solution:
const out = users.reduce(function (acc, curr) {
if(curr.age
I'm so happy that I started this series.. I feel so confident now Thank you aksay❤️💯🙌
It's the best series to learn js I have ever seen 🤩
Please upload atleast one video per week in this series 🤝
It will be very helpful 🙏
We can do something like this to get the desired output!
const filterByAge = users.reduce((acc,item)=>{
if(item.age>30){
acc.push(item.firstName);
}
return acc
},[])
but it would be good to use filter here
@@pranavparashar7137 surely, but that's not the point. The point is whether or not can we achieve the same functionality with reduce.
@@vinothkumarv9722 I love how you are trying to say you like Akshay more even when Deepika is having a crush on you✌
bro you can replace the if statement with this-
item.age>30 ? acc.push(item.firstName) : " "; return acc
ONE LINE OF CODE RIGHT !!!
@@divyansh50 sure we. Can do lie this condition rendering as well 😍
good example of reduce();
const numbers = [1, 2, 3, 4, 5];
const sum = numbers.reduce((accumulator, currentValue) => accumulator + currentValue, 0);
console.log(sum);
const names = user.reduce( (acc, curr)=> {
if(curr.age < 30) {
acc.push(curr.firstName) ;
}
return acc ;
}, []) ;
Thanks a lot, sir.. lovely explanation ❤❤
Homework :
const output = users.reduce((acc, curr) => {
if(curr.age < 30){
acc.push(curr.firstName);

I believe in Namaste Javascript supremacy! Akshay Saini for the president xD
🤐
let arr = [{fname: "first",age: 15},
{fname: "second",age:31}];
let output = arr.reduce((acc,curr)=>{
if(curr.age > 30){
acc.push(curr.fname)
}
return acc
},[]);
console.log(output);
Hi Akshay after submitted my answered then i am coming to others how they are answered
I am addicted to the way you teach and changed the way, I used to learn. Now, I always hunt the blogs which go in-depth.
Here is my H/W
// find people whose age is less than 30 using reduce
const users = [
{firstName: "Inderpreet", lastname:"singh", age:31},
{firstName: "Rahul", lastname:"Kumar", age:28},
{firstName: "Akshay", lastname:"Saini", age:20}
];
const output = users.reduce(function(acc, curr)
{
if(curr.age
Let output = user.reduce ( function (arr ,obj ){
if ( obj.age
ultimate no one can do better than this.
I would love to see object oriented classes in JavaScript and es6 modules as well
I second that, waiting for the same.
Your statement "Filter function is actually used to filter" coincided with the Ad that starts with "So you wanna be a Software Engineer at Google".
lol
const output = users.reduce(function (acc , curr) {
if(curr.age
in example 8 using initial value as arr[0] is better because it works for negative values as well and ~~ akshay saini is one of the best guru/teacher with amazing teaching skill ~~ :::::::::::: const arr = [-1,-5,-7,-2,-6,-9,-11]
const output = arr.reduce((acc, curr)=>{
if(curr > acc){
acc = curr;
}
return acc;
}, arr[0] )
console.log(output);
@Akshay Saini sir
assignment done
const output = user.reduce((acc, curr) => {
if(curr.age < 30) {
acc.push(curr.name);
}
return acc;
}, []);
console.log(output)
Nice 💯. Also you can use spread operator instead of push 😊
@@omkaranku1981 you can try acc=[...acc,curr.name] . Spread arr elements first and then the next argument should be the element you want to add.
@@mohit96nain but spread operator will create a deep copy everytime so its better to use .push()
@@omkaranku1981
const output = users.reduce((acc, user) => {
if (user.age < 30) return [...acc, user.firstName];
}, []);
Here's my solution using reduce
const output = users.reduce((result, {age, firstName}) => {
if(age < 30){
result.push(firstName);
}
return result;
}, []);
Akshay Bhaiya , Please start a small course or a bootcamp for JS from basic concepts to advanced , this content is gold , we need more of your explanation in various concepts and functional concepts. #JSbyAkshaySaini
const output = data.reduce((acc, curr) => {
if (curr.age > 30) {
acc.push(curr.name)
}
return acc;

Thank You Saree ♥ This vedio is amazing ...
last one reduce assignment:-
const output = users .reduce((acc, curr)=> firstname. age

@@saurabhgandhi615 what is thelogic of curr.age&&
Thankyou for the lesson, here is my homework 😸
const output = users.reduce(function(acc, curr){

After you've cleared all my basics, now I feel like JavaScript is like water and it's really exciting.
Solution for homework: let output = users.reduce((acc,curr) => {
if(curr.age < 30) {
acc.push(curr.firstName);
return acc;
} else {
return acc;
}
},[]);
console.log(output);
This should work. You don't need 2 return statements.
let output = users.reduce((acc,curr) => {
if(curr.age < 30) {
acc.push(curr.firstName);
}
return acc;
},[]);

Namaste JS is finally here 🔥🔥🔥
when will you release a video on the 'This' keyword in JS. We really need to understand how the binding of "this" is different in the arrow function !!
BTW, great work till now!
🙌 I am also waiting for that.
shame on you 🤣🤣🤣🤣🤣🤣🤣
Why?
Greate and in-depth teaching i ever seen.even you start it with very basic knowledge, you will get know what JavaScript is actually.
Due to other programming languages knowledge many time confusion get created, but this course played very well to teach without any confusion..
Thanks to you Akshay, this helped a lot.
Homework done sir

Video was amazing
Thanks bro
Please make video on arrow function and regular function
@Akshay Saini Sir, Can you please make a video on a small project using all these concepts, with HTML CSS JavaScript, for beginners? So that we know where and how these concepts of your previous videos are used. I know that we can google the project, but your explanation is the best and we can understand all the concepts clearly. Only if it is possible and if it doesn't bother you to show a small project. Thankyou Sir. Please consider😊
Super simple explanation
Hi Akshay Sir Thank you for sharing your knowledge I was so confused about the concepts and pull my hairs like how the things done but with your way of teaching and your support make me fall in love with the javascript and now I understand the concepts way better than before .
