Thank you for your explanation but, I would like you to clear me something how I can know which control I should set updated value? Do I should use If statement to check the control name and then set updated value to property? for example, If I have 10 controls inside formgroup should I use 10 if staments?

mobNo : []
});
}

What if we place value change in some function and which is never called. In that case it is not called. So my question, that. Do we need to call valueChange for once on init or any other way.

[jacksm]

just a question in what scenarios/scenario would one want to track the entire form? we can apply it to do what?

[sreenuksr]

any example that will talk about sending data from components to view( to html page)? if no video from this series, please share some useful links which describe the same. thank you

[omkarjadhav]

sir, how to know implement code between ngOnInit() and below ngOnInit() ?

[floydfernandes]

I'm doing something similar. I am doing it using a function on the keyup. I'm close to implementing it. My task is to replace with a blank space when the user enters anything other than 0 or 5 after decimal position. I have managed to track when this happens only the replacement part is left which must happen in realtime. Is it possible? Thanks in advance. I'm learning a lot from this series.

Waitting for Observable and rjxs operators lesson

[tejatechviews]

data => {
console.log(data);
})

Error: Object is possibly nullify

data => {
console.log(data);
})

Compilation success. But while using the get command even putting the exact form control name I am facing the Object is possibly nullify error why? while using valueChanges to all it works fine.
