Strict inequality Operator (!==)
The Strict inequality Operator is used to compare the inequality of two operands with type. If both value and type are not equal then the condition is true otherwise false.
Example: Below examples illustrate the (!==) operator in JavaScript.
// Illustration of (!==) operator
let val1 = 5;
let val2 = '5';
// Checking of operands
console.log(val1 !== 6);
console.log(val2 !== '5');
console.log(val1 !== val2);
// Check against null and boolean value
console.log(0 !== false);
console.log(0 !== null);
Output
true false true true true
JavaScript Comparison Operators
JavaScript comparison operators are essential tools for checking conditions and making decisions in your code. They are used to evaluate whether a condition is true or false by comparing variables or values. These operators play a crucial role in logical expressions, helping to determine the equality or differences between values.
In this article, we will explore the various comparison operators available in JavaScript, understand how they work, and see examples of how to use them in different scenarios. By the end, you’ll have a solid grasp of how to utilize these operators to make your JavaScript code more dynamic and responsive.
