Time for the scope chain 🕺🏼 In this post I assume you know the basics of execution contexts: I’ll soon write a post on that too though 😃

Hey @lydiahallie
let a = 11;
{
var a = 21;
}
Why this code snippet shows "SyntaxError: Identifier 'a' has already been declared "
and following code run as normal
var a = 11;
{
let a = 21;
}
var
is function scoped that is it is declared at top of the nearest function scope, global scope in the first one, where alreadya
is present .let
is block scoped that is it is scoped inside nearest flower brackets.var a
is in global scope andlet a
is in block scope.muito bom , ou seja meu escopo que seria minha função declarada com "chaves"
const a = 'hi'
function myFunction() {
// pode ter acesso a todos que estão de fora da minha função
const x = 'ana'
console.log(a) -> 'hi'
}
// mas quem está de fora não consegue acessar os valores de dentro da minha função
// console.log(x) -> undefined
Another awesome content! Thanks!
Extremely helpful, please keep this good stuff going. Your content should get more exposure to others.
Great article. I guess you missed to mention, var has function scope.
Really useful information!
Hi @theavocoder how can i learn and strong my fundamental javascript and advance javascript. please share resources.
Does the same methodology apply to telescopes 🔭
u need a microscope
You introduced the "local scope chain", "activation object" and "global object". What has that to do with the "local execution context"?
esto es una JOYA, que buena explicación
thanks
You're a life saver , that was dope content 🔥🔥
What happen if we call the getPersonInfo() function somewhere. Will they be saved in the execution context?
