Q:

js variable

//choose the best for your solution
var myVariable = 22; //this can be a string or number. var is globally defined

let myVariable = 22; //this can be a string or number. let is block scoped

const myVariable = 22; //this can be a string or number. const is block scoped and can't be reassigned

var Number = 5;
var String = "Hi!";
var boolen1 = true;
var boolen2 = false;
var array = [11, "Hi!", true];
var object = {age:11, speach:"Hi!", likes_Bananas:true};
3
var <variable-name>;

var <variable-name> = <value>;
3
//You can make a variable by using:
var variable-name = 'defenition of the variable';
// Or you can use
let variable-name = 'defenition of the variable';
1
//Assigns the value bar to the variable foo
var foo = bar;
1
var variable1 = "some variable content";
1
var user_name = prompt("Please enter your name:", "Type here");
alert("Hello " + user_name);
1
// write what ever you want
// one way is
// this is to declare intigers
var a = 10;
//this is to declare strings aka words
var b = "hi";
// the key word var can be replaced by let
//like this
let a = 10;
let b = "hi";
// i recomend using let insted of var
4
// let & var are both editable variables:
var cow = 'moo';
let pig = 'oink';
cow = 10;
pig = 10;
// const is a permanent variable; you cannot change it.
const uncuttableGrass = '\/\/';
uncuttableGrass = '___';
// above throws an error
