Is there “0b” or something similar to represent a binary number in Javascript

Question

I know that 0x is a prefix for hexadecimal numbers in Javascript. For example, 0xFF stands for the number 255.

Is there something similar f

Answer 1

If your primary concern is display rather than coding, there's a built-in conversion system you can use:

var num = 255;
document.writeln(num.toString(16)); // Outputs: "ff"
document.writeln(num.toString(8)); // Outputs: "377"
document.writeln(num.toString(2)); // Outputs: "11111111"
