I have this string returned to me 2022/2/23. And some other times 2022/2/23 16:32:23. I want to make this: if dateString has no time in it then blabla.

How can I check if my string has a time string in it?

I'd consider using a JS regex. For example: stackoverflow.com/a/38403498/421195

【解决方案1】：

Try using includes to check if there is a : present:

const checkIfIncludesTime = (dateStr: string): boolean => dateStr.includes(':');

You can also use regex for this one:

const checkIfIncludesTime = (dateStr: string): boolean => /:/.test(dateStr);

Hope this helps
