I need a regex that can capture strings in groups of three, but if the remaining characters are not divisible by three, I want them grouped in twos.
For example:
123456 should be 123 4561234567891011 should be 123 456 789 10 11Could someone please assist me with this?
I attempted (.{1,3})(.{3}|.{2}) but it didn't work as expected.
You may want to consider using a positive lookahead for two characters.
const modify = text => text.replace(/.{2,3}(?=..)/g, '$& ')
console.log(['12', '123', '1234', '12345', '123456', '1234567', '12345678', '123456789', '1234567890'].map(modify));Give this a shot:
(?=\d{5})(\d{3})|(\d{2})
