Question : how to declare a variable js
Answered by : magnificent-mockingbird-0ruhlo6absrf
//let and var are both editable variables and can be changed later on in your program;
let dog = 'Woof';
//dog is equal to the string 'Woof';
dog = false;
//You can changed the value of dog now because it was defined with let and not const;
let cow = 'Moo';
//cow is equal to the string 'Moo';
cow = true;
//You can change the value of cow later on because it is not defined with const;
//const is used when declaring a variable that can't be changed later on -- const stands for constant;
const pig = 'oink';
//This assigns the string 'oink' to pig which can not be changed because it is defined with const;
pig = 'snort';
//Above throws an error
//Good Job you now know how to declare variables using JavaScript!!!

//variables are declared by the var keyword, example...
var x = 10;
//or
var dog_name = "daisy";

Answered by : mohammad-alshraideh
/*Variables declared with var, let and const are quite similar when declared outside a block.
They all have Global Scope:*/
var x = 2; // Global scope
let x = 2; // Global scope
const x = 2; // Global scope
