I'm trying to remove the fullstops, commas and spaces from a string. I'm pretty sure I have to do this using this: str.replace(<some Regex here>, "");
I'm just not very familiar with Regex, how can I accomplish this?

Use this regex /[.,\s]/g
var str = 'abc abc a, .aa ';
var regex = /[.,\s]/g;
var result = str.replace(regex, '');
console.log(result);You don't need to escape character except ^-]\ in character class []
Any character except ^-]\ add that character to the possible matches for the character class.

You don't need the backslash before the
. in the brackets unless you're escaping the ] since the matches are literal.timolawl
Ah. Amending my comment above to include that it is also necessary to escape backspace itself because it will escape other characters. Cheers.

Sorry I meant backslash \. Pretty tired right now. Not directly relevant to the question, but meant in general in case for future readers since my above comment is only partially correct.

I was attempting to clarify that this is another exception that needed escaping in addition to
] and ^ within regex square brackets if trying to literally match those characters. Maybe a few others I missed. Not relevant to the question or answer; just correcting my above comment.I believe this should do it:
str.replace(/[.,\s]/g, '');

Something like this should work...
str=str.replace(/./g,'').replace(/,/g,'').replace(/ /g,'');
