ngif incorrectly evaluates a simple boolean

[frozen trout]

Can someone explains me what is wrong here ? There is obviously something wrong here but cant find it...

<td class="text-center"><i *ngIf="lps.fast" class="fas fa-check"></i>{{lps.fast}}</td>
Always evaluates to true even when lps.fast (which is a boolean) is false

Watch captures for detail

Hello @frozen trout , check the value: is it false or "false"?

[frozen trout]

it is a boolean, so false and not "false"

[rare sparrow]

is it coming from an api call?

[frozen trout]

yes

Typescript can't assert data coming from an api call, I encourage you to check with Network tab if fast is really a boolean.

Because that would be the only reason for your situation

[frozen trout]

yes that was it, silly me

the attribute was a string ad not a boolean :/

thanks for your fresh eye, I was becoming mad 😄

And now we have Signals to help us getting confused the time to get it to it ^^ @if(mySignal) {}

I think you get a diagnostic about that 🙂
