boolean operators javascript 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: and operator in javascript
//&& returns true if both values are true
//or returns the second argument if the first is true
var a = true
var b = ""
var c = 1
true && "" //""
"" && 1 //""
false && 5 //false
Example 4: 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
Example 5: and operator in javascript
//& (bitwise AND) operator
console.log(5 & 13); //outout: 5
/*
5 = 0101 (base 2)
13 = 1101 (base 2)
//AND every bit together from both numbers
+----+
|0101|
|1101|
