Wow, that's amazing Adam thank you - the map function is really powerful. I thought there would be an elegant functional way to achieve this!

I know this is a little hacky, but I thought it was an interesting solution.
function dataStringToArray(str) {
return JSON.parse( '[[' + str.replace( /\|/g, '],[' ) + ']]' );
}
Given a string in this format:
"1,15|22,22|24,19|44,33"
return in nested array:
[[1,15][22,22][24,19][44,33]]
