ng class vs class binding difference in angular ?

Some when we work both seems to be same but there is difference we will see with example with implementation code.

Component

1. Style — scss

 .value {
   background-color: yellow;
  }
  .integer {
    color: green;
  }
  .number{
    border: 2px solid black;
  }

2. template — html

  <div class="value" [class]="['integer number']">
    Label Class 10.5
  </div>

  <div class="value" [ngClass]="['integer number']">
    Label ng class 10.5
  </div>

so class will work with array of classes but ngClass works

but if we change

<div class="value" [class]="['integer', 'number']">
Label Class 10.5
</div>
<div class="value" [ngClass]="['integer number']">
Label ng class 10.5
</div>

it apply.

…..

So till now found this syntax difference. more still add…soon
