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

No, but you can use parseInt and optionally omit the quotes.

parseInt(110, 2); // this is 6 
parseInt("110", 2); // this is also 6

The only disadvantage of omitting the quotes is that, for very large numbers, you will overflow faster:

parseInt(10000000000000000000000, 2); // this gives 1
parseInt("10000000000000000000000", 2); // this gives 4194304
