It is straightforward in javascript you can use the code below but you need to handle failure cases based on your requirements else you can use the npm package which provides ascii-text-converter with all error handling.

function AsciiToText(ascii: string) {
  const asciiArray = ascii
    .split(" ")
    .map((code) => parseInt(code.trim(), 10))
    .filter((item) => !isNaN(item));

  const sentence = asciiArray
    .map((asciiValue) => String.fromCharCode(asciiValue))
    .join("");

  return sentence;
}

Here's a simple function(ES6) which converts a string into ASCII characters using charCodeAt()

const toAscii = (string) => string.split('').map(char=>char.charCodeAt(0)).join(" ")

console.log(toAscii("Hello, World"))

Output:

-> 72 101 108 108 111 44 32 87 111 114 108 100

You could create a prototype function aswell. There are many solutions :)

you can't have an ascii code for a whole string.

An ascii code is an integer value for a character, not a string. Then for your string "0170" you will get 4 ascii codes

you can display these ascii codes like this 

var str = "0170";

for (var i = 0, len = str.length; i < len; i++) {
    console.log(str[i].charCodeAt());
}

Ouput : 48 49 55 48

use charCodeAt() function to covert asscii format.

var ll = "0170";
function ascii (a) { return a.charCodeAt(); }
console.log(ascii(ll[0]),ascii(ll[1]), ascii(ll[2]), ascii(ll[3]) )

result:

48 49 55 48
