chunk/split a string in Javascript without breaking words

Question

Good day,

I would like to know if there is an easy way to chunk/split a string without breaking the words.

Eg:

var input = \"Lorem ipsum dolo         


        

Answer 1

Something like this?

var n = 80;

while (n) { 
    if (input[n++] == ' ') { 
        break;  
    } 
}

output = input.substring(0,n).split(' ');
console.log(output);

UPDATED

Now that I re-read the question, here's an updated solution:

var len = 80;
var curr = len;
var prev = 0;

output = [];

while (input[curr]) {
    if (input[curr++] == ' ') {
        output.push(input.substring(prev,curr));
        prev = curr;
        curr += len;
    }
}
output.push(input.substr(prev));
