You can see in the about section.
hai, bro. thanks for your teaching way .but still, I not able to understand let and var bro.I am getting doubt. we can initiate it, var and let local and global right.
var is a function scope and let is a block scope. we can use let also function scope right with the global declaration. then, var also we can use local and global and let also we can use local and global. but still, I am getting confusion.
1).VAR Example.
var a=2
function local()
{
var a=10;
console.log(a);
}
console.log(a);
2) let example:
let a=2
function local()
{
let a=10;
console.log(a);
}
console.log(a);
I am getting output var and let the same output. if I use local and global var and let. then what is the difference between var and let?
Example 1 -> if you dont declare var a=10 in function, you can get output is 2 and 2, Example 2 -> if you dont declare var a=10 in function, you can get output is undefined and 2.
hi bro...
