How to check type of variable in ngIf in Angular2

Question

I\'m learning Angular2. I have a component with a variable which is an object. I\'m iterating over the fields of the object, and acording to the type of data of that positio

Answer 1

I just tried this and found it won't work in production because function names are shortened. It's safer to use something like:

foo instanceof FooClass

But note that you have to do this in the component/directive because instanceOf is not available in templating:

// In your component
isFoo(candidate){
    return candidate instanceof FooClass;
}

// in your template
{{isFoo(maybeFoo)}}
