javascript string comparison code example

Example 1: javascript compare number to string

let string = "1";
let number = 1;
if (parseInt(string) === number){
  	// STRING AND NUMBER MATCHES
}
if (string == number){
  // STRING AND NUMBER MATCHES ALSO BECAUSE == instead of ===, means it won't compare datasets, only the content
}

Example 2: string comparison in javascript

var str1 = "ab";
var str2 = "ab";
var n = str1.localeCompare(str2);

Example 3: eaqual signs in javascript

//x = 5

operator  |	example	 |	output  |	explination

==			x == 8		false		equal to
			x == 5		true
			x == "5"	true

===			x === 5		true		equal value and type
			x === "5"	false

!=			x != 8		true		not equal

!==			x !== 5		false		not equal value or not equal type
			x !== "5"	true
			x !== 8		true

>			x > 8		false		greater than

<			x < 8		true		less than

>=			x >= 8		false		greater than or equal to

<=			x <= 8		true		less than or equal to

Example 4: js ===

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

Example 5: equal to or more than javascript

//Equal to or more than
a >= b
//Equal to or less than
a <= b

Example 6: less than equal to in javascript

| <= | less than or equal to |	x <= 8 | true |
