JavaScript regex to split numbers and letters

Question

I need regex pattern to split a string into numbers and letters. I.e. .1abc2.5efg3mno should be split into [".1","abc","2.5","efg","3","mno"].

The current regex I tried is:

var str = ".1abc2.5efg3mno";
regexStr= str.match(/[a-zA-Z]+|[0-9]+(?:\.[0-9]+|)/g);

Output obtained is:

["1","abc","2.5","efg","3","mno"]

The number .1 is taken as 1 whereas I need it as .1.

Answer 1

If it's a matter of separating letters from non-letters, then the regex can be made quite simple:

var str = ".1abc2.5efg3mno";
var regexStr = str.match(/[a-z]+|[^a-z]+/gi);
console.log(regexStr);

I.e. match a group of letters or a group of non-letters.
