JavaScript Are [(ngModel)] bindings always strings?

No it isn't always a string. And by the way, that's the first time I see a tag without quotes !

When you make a compoment with an input like this

<app-my-component firstVariable="hello world"></app-my-component>

Then it's a string. You can't even give a variable in this case, the input will have the variable's name as value.

But if you do

<app-my-component [firstVariable]="hello world"></app-my-component>

Then it won't work. Because here, you're supposed to give a variable. To make it work, use this

<app-my-component [firstVariable]="'Hello world'"></app-my-component>

Now, you're giving something like an "anonymous variable" : you use quotes, so Angular understands it's a string.

In your case, you use a radio button. Radio buttons are part of radio button groups, and each of them have string values. So even if you write true, that doesn't mean it's a boolean ! If you want to give it a boolean, you will have to use

[value]="true" 

I hope I helped !
