NgClass vs Class [duplicate]

Question

I wonder when should use ngClass instead class I noticed that this style in css file

.someClass {
  color: red;
}

<div [ngClass]="['someClass']">Some text</div>
<div class="someClass">Some text2</div>

working properly for two div with diff aproach. I write that when we use condition is good practice using [ngClass]. Why else? What are the benefits using [ngClass] instead class ?

Answer 1

using ngClass we can use expressing for class, for example, if you want to use a condition based class then need to use ng-class

<button ng-class="row.bstatus?'btn red btn-outline':'btn green-haze btn-outline'">{{row.bstatus?'Deactivate':'Activate' }}</button>

Answer 2

Not much benefit using it to put the single literal class name. The benefit would be to use it to dynamically set the class.
