Angular: conditional class with *ngClass

Question

What is wrong with my Angular code? I am getting:

Cannot read property \'remove\' of undefined at BrowserDomAdapter.removeClass ...

Answer 1

You can use [ngClass] or [class.classname], both will work the same.
[class.my-class]="step==='step1'"

   OR

[ngClass]="{'my-class': step=='step1'}"

Both will work the same!
