JS does not have any builtin morse library, therefore we need to build it in order to use a simple oneliner:
m = { '.-': 'A', '-...': 'B', '-.-.': 'C', '-..': 'D', '.': 'E', '..-.': 'F', '--.': 'G', '....': 'H', '..': 'I', '.---': 'J', '-.-': 'K', '.-..': 'L', '--': 'M', '-.': 'N', '---': 'O', '.--.': 'P', '--.-': 'Q', '.-.': 'R', '...': 'S', '-': 'T', '..-': 'U', '...-': 'V', '.--': 'W', '-..-': 'X', '-.--': 'Y', '--..': 'Z', '-----': '0', '.----': 1, '..---': 2, '...--': 3, '....-': 4, '.....': 5, '-....': 6, '--...': 7, '---..': 8, '----.': 9 }; decodeMorse=(s)=>s.split(' ').map(e=>m[e]||'?').join('')
And the result is:
decodeMorse('.... . -.-- .--- ..- -.. .') "HEYJUDE" // Unknown values are handled decodeMorse('...... . -.-- .--- ..- -.. .') "?EYJUDE" // And it doesn't affect "falsey" values decodeMorse('...... ----- -.-- .--- ..- -.. .') "?0YJUDE"
And here goes the encoder, using the same m variable as above
m
encodeMorse=(s)=>Object.entries(m).map(e=>s=s.replace(RegExp(e[1],'gi'),' '+e[0]))&&s.slice(1)
The encoder produces the following result:
encodeMorse('HEYJUDE') ".... . -.-- .--- ..- -.. ." encodeMorse('heyjude') ".... . -.-- .--- ..- -.. ."
