Extract strings in a .txt file with javascript

I have a .txt file with this structure:

chair 102
file 38
green 304
... ...

It has 140.000 elements.

Before introducing the numbers I used javascript and jQuery:

$(function () {
        $.get('/words.txt', function (data) {
            words = data.split('\n');

        });

But because I have now numbers how could I treat separately the strings and the numbers?

An efficient way of handling this problem is to replace all the line breaks with spaces, then split the resulting string by the spaces. Then use what you know about the position of the elements to determine whether you're dealing with a number or a string:

var resultArr = data.replace(/\n/g, " ").split(" ")

for(var i = 0; i < resultArr.length; i++) {

    if(i % 2) {
        // even indexes represent the word
        console.info("word = " + resultArr[i]);
    } else {
        // odd indexes represent the number 
        console.info("number = " + resultArr[i]);

    }

}

Depending on whether or not there's a line break at the end of the set, you may need to handle that case by looking for an empty string.

you could split at each new line and then split each element at space, but this will gives you array of array of words .

you could replace line with space and then split at space ie:

words = data.replace(/\n/g,' ').split(' ');

Since this helped, I'll post as an answer:

Your format is <word><space><num>\n You split on new line, so now you have an array of <word><space><num> which you should be able to split on space.

Then you can get the word part as myarray[0] and the number part as myarray[1].
