I am trying to learn pure javascript and stumbled upon the topic of let and var keyword. Based on my understanding, let has a local scope and var has global scope even if it is declared in an inner block of code.
The problem was in the following code.
let glob='global'
if(true){
var local='local'
console.log(local)
glob='inlocal'
console.log(glob)
let glob='local'
console.log(glob)
}
console.log(local)
console.log(glob)
The above gives the error 'glob is not defined' at the line glob='inlocal'
As the glob is declared in the outer block, shouldn't it value be updated?
Also, when I commented the lines
let glob='local'
console.log(glob)
There was no error for the code. I don't understand why this effect is there.
