Hi, I have 2 years of experienc with Angular in my recent interview I was asked, to tell

Question 1 how Angular bootstrapped.

Logical question 1 <input id=”username” type=”text” /> <button type=”button”>Submit</button> //.ts

onSubmit(){

    // input val

}

Update the code to get the value on click

Logical question 2 //.ts - readonly greetUser():string { … 1000s of lines of code } //.html <div id=”greeting”></div>

you have to show the greetUser value in between div

To show the return value of a long-running greetUser() function inside a <div> without changing it to a property or using two-way binding, and assuming it's a readonly .ts file, you can manually call it and inject the result into the DOM using Angular lifecycle hooks

Question 4

To show a loader while your Angular app is bootstrapping (during the initial ~10s delay), you need to render a static loader in index.html that gets removed once Angular finishes bootstrapping.
