java script logical operators code example

Example 1: or operator in javascript

//The OR operator in Javascript is 2 verticals lines: ||

var a = true;
var b = false;

if(a || b) {
	//one of them is true, code inside this block will be executed
}

Example 2: js ===

5 =='5' // true: ignores type
5 === '5' // false: includes type

Example 3: js !==

var x = 5;

// === 	equal value and equal type
// e.g. 1. 
x === 5 returns true

// e.g. 2.
x === "5" returns false

// !== not equal value or not equal type
// e.g. 1.
x !== 5 returns false

// e.g. 2.
x !== "5" returns true

// e.g. 3.
x !== 8 returns true
