How do I test a string that contains a character at the start then a space and whatever comes after that which could be an integer or float?
Example:
'$ 15'
'$ 15.95'
/\$\s[\d]*\.[\d]{2}|\$\s[\d]*[^.]/gm
$space(endless digits until)period and exactly-2digits
|OR
$space(endless digits-no periods)
const rgx = /\$\s[\d]*\.[\d]{2}|\$\s[\d]*[^.]/gm;
const str = `\$ 15.95 \$ 5 \$ 2.00
\$ 6.90 \$ 1101`;
let matches = [...str.matchAll(rgx)].flat();
console.log(matches);I think it could help you: ^\$ [+-]?[0-9]{1,}(\.[0-9]{1,}){0,1}, you can test it here: https://regex101.com/
^\$: start with a character[+-]? then add optional signs[0-9]{1,} then add at less one digit(\.[0-9]{1,}){0,1} then add a dot and at less one digitYou can use below regular expression :
. \d+(?:.\d+)?
