How to find all characters after a dot?

Question

JavaScript

Goodnight. I need to remove all characters after the dot, I tried like this:

text.replace(/\.*\*/, "");
// И вот так
text.replace(/\.*\./, "");

But it doesn't work, it doesn't even return anything to the console!
How to do it?

Answer 1

var text = 'test.test1111';
console.log(text.split('.')[0]);

Answer 2

Perhaps it's time to write an article on Habr about the harmfulness of RegExp. Your misunderstanding of what happens in the simplest regular season only proves it. And I will answer you, like many others before you, that you do not need RegExp, because it is very expensive, both in calculation and in support.

I need to remove all characters after the dot

const p = text.indexOf('.');
const result = p === -1 ? text : text.slice(0, p);
console.log(result);

tried like this:text.replace(/\[.][A-Z]/, "");

This regular expression will find the first dot immediately followed by a capital Latin letter and cut out only this particular combination, which does not correspond to the question at all.
