Take a look at this:
[ngClass]="{className: singleNumber == arrayOfNumbers}
Is there a way to compare 1 === [1,2,3,4] ? It seems to work if I use arrayOfNumbers[0]
Take a look at this:

Is there a way to compare 1 === [1,2,3,4] ? It seems to work if I use arrayOfNumbers[0]
Why not simplify the process by comparing in the typescript file and then checking the boolean value in the template?
HTML
[class.className]="isInArray"
TS
arrayOfNumbers = [1,2,3,4];
//place where you want to trigger the check
foo(myNumber: number) {
this.isInArray = this.arrayOfNumbers.indexOf(myNumber) !== -1
}
Here is a solution to address the current scenario
[ngClass] ="{ styleName : numbersArray.contains(number) }
