You can use a regex like below to test if the given string is a URL or not.

```js
let regex = /^https?:\/\/(?:www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)$/gm;

console.log(regex.test('https://onecompiler.com/javascript'));
console.log(regex.test('https:onecompiler.com/javascript'));
```
