Convert From/To Binary/Decimal/Hexadecimal in JavaScript + calculate byte length

baseConverter.js

const convert = {
  bin2dec : s => parseInt(s, 2).toString(10),
  bin2hex : s => parseInt(s, 2).toString(16),
  dec2bin : s => parseInt(s, 10).toString(2),
  dec2hex : s => parseInt(s, 10).toString(16),
  hex2bin : s => parseInt(s, 16).toString(2),
  hex2dec : s => parseInt(s, 16).toString(10),
  lenBytesDec: bin => (bin.length/8).toString(10),
  lenBytesHex: bin => (bin.length/8).toString(16),
