I have a text file (separated by ', ' between each word) and a function that assigns a word a value (where a = 1, z = 26) when it is run. (ex: sumChars('JavaScript') returns 119.) My question is, how do I get only the first word, run the function with that, and move on to the next word? I know that after using fetch(url) to get the file, I can use .then(d => d.replace(/\n/, '')).then(d => d.replace("', '", '')) to get rid of everything else.

    try to split your string into an array then call your function to each element: `const resp = d.split(', ').map(x => sumChars(x))` – guijob Jan 22 '19 at 23:36

The best way to deal with strings in Javascript is to use regular expression, with g (global) flag to process all ocurrences in the string.

var list = [], sums = [];

fetch(url) 
 .then(txt => list = txt.replace(/\n/g, '').replace(/\s/g, '').split(","); return list;)
 .then(res => res.forEach((wrd,idx,arr) => { sums[idx]=0; 
 wrd.split('').forEach(char => sums[idx] += char.charCodeAt(0)-96)}) 
    );

console.log("result: ", list,sums);

As a reference to get characters value convert characters to ascii code.
As a reference to bind array elements in foreach loop foreach loop by reference.
