Hoisting Q1

Question

a();

function a(){
    console.log('hi');
}

function a(){
    console.log('bye');
}

Thoughts

• My initial though would be that the function gets reassigned?

• If the hoisting moves up, during the first pass?

a = undefined

function a = () {
} ?

function a = () {
} ?

• My thought process is that because the function is hoisted up and then reassigned, then the function scope is whatever is the latest function?

Answer

Functions are hoisted with their scope, they are also replaced (overwritten) if there's another declaration

a();

function a(){
    console.log('hi');
}

function a(){
    console.log('bye');
}

Can be translated to during the first pass:

a() // first function 
a() // second function


function a(){}
function a(){} 

///

// This means that the second declaration of the func
// would overwrite the first. 

a() // bye
