Less-than Operator

In JavaScript, Less-than comparison operator takes two operands, returns true if value in left side operand is less than that of the right operand, or false otherwise.

Syntax

< symbol is used for less-than operator.

a < 5  //returns true if a has a value < 5
a < b  //returns true if a has a value < b

Examples

1. Check if value in a is less than 5.

var a = 3;
if (a < 5) {
    console.log('a is less than 5');
} else {
    console.log('a is not less than 5');
}

2. Check if value in a is less than that of in b.

var a = 9;
var b = 4;
if (a < b) {
    console.log('a is less than b');
} else {
    console.log('a is not less than b');
}
