JS/ Regex A better way to get RGBa values from a string

Question

I'm using this code to convert a string like "rgb(200, 12, 53, 0.96)"to an array of numbers

this is my code

var rgb = 'rgb(200, 12, 53, 0.96)'.match(/\d+/g);
console.log(rgb);

but the output wrongly push 0 and 96 as separate values

how can I keep floating numbers together? i have no idea how regex works sorry

maybe with simple var rgb = 'rgb(200, 12, 53, 0.96)'.match(/[\d\.]+/g); — kip

0.96 contains a decimal that doesn't match \d, you can add . with \d in a character class wrapped in [] to match float numbers:

var rgb = 'rgb(200, 12, 53, 0.96)'.match(/[.\d]+/g);
console.log(rgb);
