How to convert a file's content into array in JavaScript?

Question

I have file called "temperatures.txt". It includes the text:

22,
21,
23

How do I copy the file's content into a JavaScript array?

var temperatures = [22, 21, 23];

Read file content, split it's content on \r\n and you have JS array. — Justinas

@HappyJoe - are the commas actually a part of the file? And is the file actually split onto new lines as you've shown? — random_user_name

If your text looks like this

var txt = "22,21,23";

you can convert it to an array like this

var array = txt.split(',');

or, if theres also a new line do

var array = txt.split(',\n');

Your text

var mytxt = "10,20,30";

Convert into array

var array = mytxt .split(',');

var str = "22,\
           21,\
           23";

// this will remove spaces as well
var result = str.split(/\s*,\s*/);

console.log(result);
