angular - Change classes conditionally Ionic2

I want to change my classe for an element but I don't know how to process with Ionic 2. I tried this way but it's wrong :

<span [ngClass]="{(user.id == this.session.userDefaultId) : 'class1 class2', (user.id != this.session.userDefaultId) : 'class3 class4'}">
...
</span>

Someone can explain me how to do somethink like that please ? :)

You can use a simple ternary operator to set the class for your example.

<span [ngClass]="(user.id == this.session.userDefaultId) ? 'class1 class2' : 'class3 class4'">
...
</span>
