There isn't an equivalent for binary numbers in Javascript. However you can have binary string converts into decimal using parseInt function. console.log(parseInt('1101', 2)); // output decimal 13

var bin = prompt('Enter a binary number (only 0 and 1, none prefix)?'); var dec = 0; var i = bin.length; while (i--) { if (bin[i]=='1') dec += Math.pow(2,(bin.length-i-1)); } alert(dec);
