sign of != "" in js 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: not equal to in js

let a=12
if(a!=5){
  console.log(true)
}
since a is not equal to 5, it will print true
