Question

So I’ve got an array that has thousands of values. The delimiter is the same and the content is all numbers. It’s a simple array.

Example..

[491353764,202825540,338196858] 

Imagine that is 15000 values. I need to split the array into multiple groups of 100 strings.

I got the first 100 fine using this:

ids = ids.toString();
ids = ids.split(',', 100);
console.log(ids.toString());

I know this is basic stuff, but I couldn’t find anything that would allow me to split it multiple times into groups. Am I focusing on the wrong thing thinking some version of split will do the job? Do I need to put it through a loop?

Answer 1

I assume you want to store the groups of 100 in another Array…

var ids = [/* your large array of numbers */];

var array_of_sets = [];

while( ids.length ) {
    array_of_sets.push( ids.splice(0, 100) );
}
