Well explained, straight forward on point, logical and understandable, no stupid unneccessary talking :) Thank you!

We can use a global const variable in which we can assign the domain name . by which we dont have to change the name in the validationMessage also.

Sir, can you make me understand, even we are getting single parameter in outer fuction then inner how the second parameter control is accessible in the inner function. I mean we are just getting single parameter at outer function.

Hi. I have a query. Is it prerequisite to learn angular 5 before learning angular 6?
And nice videos as always :)

If you want to trigger this validator on demand and want the parameter to be dynamic it won't work, as the validator is taking only the first value of the parameter into consideration and does not look for changes.

Angular Reactive approach is so much bloated. In Template driven approach we just need to create a Directive implementing Validator Interface and add it in Template.
