New Number Methods
- Number.isInteger() Method: It checks if a value is an integer, returning true if it is, false otherwise.
- Number.isSafeInteger() Method: It verifies if a value is within the range of safe integers, preventing precision loss.
Example: In this example we are using the above-mentioned method.
Javascript
const num1 = 42; const num2 = 3.14; const num3 = 9007199254740992; // Largest safe integer console.log(Number.isInteger(num1)); console.log(Number.isInteger(num2)); console.log(Number.isSafeInteger(num1)); console.log(Number.isSafeInteger(num3)); |
Output
true false true false
JS 2015 or ECMAScript 6 (ES6)
JS 2015 (ES6) also known as ECMAScript 6 (ES6), ECMAScript 6 (ES6) is a significant update to JavaScript, introducing arrow functions, classes, template literals, let and const for variable declaration, enhanced object literals, destructuring, and more modern features for better code organization and readability.
