Question

I have an array of characters:

var separators = ['a', 'b', 'c'];

I want to split a string by any of the characters in this array. For instance,

var str = 'adbasscdabda';

should become

var splitUpArray = ['d', 'ss', 'd', 'd'];

How do I achieve this? I have tried splitting the string by one character at a time and then concatenating the subarrays together, but this seems unwieldy.

For this example you can use .match method:

var str = 'adbasscdabda';

str.match(/[^abc]+/g); // ["d", "ss", "d", "d"]

A more universal solution:

var separators = ['a', 'b', 'c'];
var re = RegExp('[^' + separators.join('') + ']+', 'g');
var str = 'adbasscdabda';

str.match(re); // ["d", "ss", "d", "d"]
