Tag: Lexical Scope

In this short video tutorial I explain what is meant by Lexical Scoping.

Sample code snippet used for explaining.

// Lexical Scope
// Code in one scope can access variables in same scope or any scope outside // of it.

// Global variables
let x = 2

// function with an inner function
function outerFn() {
let y = 9
// can access x, y

function innerFn () {
let z = 44
// can access x,y,z
console.log(x, y, z)
}
}
