Regex to replace dots with new line but not for number-CodePudding

I have the following regex will replace dot with a new line

But what if I want to skip numbers

var mystring = 'okay.this.is.a.string';
mystring = mystring.replace(/\./g,'\n')

But what if there are numbers, I want to skip

var mystring = 'okay.this.is.a.string.This.is.a.number.123.23';

I want to keep the number 123.23 without going to a new line

Please let me know how to write an updated regex for this.

CodePudding user response：

You can replace all the occurence in notepad by adding

But be sure to put cursor on the beginnin of the line from where you want to replace. If you want to replace all the occurence in whole document, then you should put your cursor and then replace it

Find what: (?<!\d)\.

Replace with: \n

1) You can use Negative lookbehind here as:

const str = `okay.this.is.a.string.This.is.a.number.123.23`;
const regex = /([^\d])\./g;

console.log(str.replace(regex, "$1\n"));
