Validate Mobile Number function

common.js

    validateMobile(phone) {
        const pattern = /^([0]|\+91)?[6789]\d{9}$/;  //Regex Valid for all Indian mobile numbers
        if (!isNaN(phone) &&  phone.match(pattern) ) return true;
        return false;
        }
      },

Nice 👏

Some suggestions:

• There are some syntax error which will prevent this from running.
• You can slightly shorten the regexp: /^([0]|\+91)?[6-9]\d{9}$/
• Instead of phone.match(pattern), use pattern.test(phone) as it returns a boolean value.
• No need of the if clause, you can simply do this: return (!isNaN(phone) && pattern.test(phone))

Nice clap

* Instead of `phone.match(pattern)`, use `pattern.test(phone)` as it returns a boolean value.

Got it ! .
