Javascript Form Validation with *

Question

I'm using a name validation in Javascript. I found this code on internet. It's working fine.

I'm not getting why do we need to use the asterisk(*) symbol here? Code is not working without this also.

var pattern=/^([A-Za-z ]*)$/g;

It's to matches any length of that capture group (([A-Za-z ])). I would recommend https://regexr.com/ if you run in to problems with regex as it includes a good explanation for all expressions

It Matches the preceding item "x" 0 or more times in ([A-Za-z ]). Read this : Quantifiers in Javascript
