How to represent binary numbers in JavaScript?

Binary numbers are represented by 0 followed by small (or) capital B followed by the binary digits.

Example

0b111

0B1010

HelloWorld.js

var x = 0B1010;
var y = 0b111;

console.log("x : " + x);
console.log("y : " + y);

Output

x : 10

y : 7

If the digits after 0b (or) 0B contains non-binary digits (0, 1), then you will endup in SyntaxError.
