HTML-код
- Опубликовано: 21 авг 2024
- Hoisting in JavaScript is the most famous Interview Question.
Hoisting as a core concept relies on the way how Execution Context is created. In the first phase i.e. the Memory Allocation Phase all the variables and functions are allocated memory, even before any code is executed. All the variables are assigned undefined at this point in time in the local memory.

Reduce size ऑफ circle in video
Because of Js Code execution complited in 2 phase. And every functions and variable in program JSEngin Trite as a Key:Value pair.
That's why hosting comes into picture.
Because in first phase JSEngin get a memory in a variable and assign undefine. And JsEngine also set function name as key and function body as a value.
That's why if call a function before defination its execute smoothly.
Because body of the function is set in first phase.
And if you try to log our variable you get undefined.
Because Assignment of variable conplited in second phase.
But if you not declared a variable and try to using this variable JSEngin get error.
Its only happen when JSEngin not get memory(Reference) into this variable.
That's why JSEngin get reference error
"Hosting is all about a memory management Or dealing with memory."
