JavaScript Logical And(&&) Operator or Logical Conjunction Operator operates on a set of operands and returns true only if all the operands are true otherwise returns false. It operates the operands from left to right and returns false whenever the first falsy value is encountered.
The Logical AND(&&) Operator can also be used on non-boolean values also. AND operator has higher precedence than the OR operator.
Syntax:
a&&b
Example 1: In this example, we will use the AND operator on normal values.
Javascript
console.log(true && false); console.log(true && true); console.log(1 && 0); console.log(1 && 2); console.log("1" && true); console.log("0" && true); |
Output:
false true 0 2 true true
Example 2: In this example, we will use the AND operator on function calls
Javascript
function a () { return true; } function b () { return true; } console.log(a() && b()); |
Output:
true
