JavaScript - number multi split

Question

I have a number in JS like 2,5 or 2.5

I want to use a multi split like

'2.5'.split(/,|./)

but it gives me the wrong output, why ?:

["", "", "", ""]

/,|./ is incorrect regex. It should be in a charatcer class /[,.]/ or be escaped /,|\./

This works: '2.5'.split(/[.,]/)
