Split a string at each number

Question

The idea is to take a string of letters and numbers much like an algebraic expression with indices and split them up while including the index with the corresponding letter. For example: You take the expresson 2x^3 and it would be split into an array like so ["2","x^3"]

As of right now I have tried to work with the letters and the number can come later but this is what I have got so far:

expression.split(/([a-z])/);

This takes the string and splits it at every number. I'm not good at regular expression so some help on including the index of a letter with the split would be much appreciated.

Answer 1

Here is what you are looking for :

var string = '2x^3ui3+3-ddez2';
var regex = /(\D*\d)/g;
var array = string.match(regex);
