Is there a simple way to compare multiple values to a single value in Javascript ?
Like, instead of writing :
if (k != 2 && k != 3 && k!= 7 && k!12)
Writing something like :
if (k != {2,3,7,12})
You can use includes instead of multiple equality comparisons.
if (![2,3,7,12].includes(k))
That's boolean algebra:
if (k != 2 && k != 3 && k!= 7 && k != 12)
is equivalent to
if (!(k == 2 || k == 3 || k == 7 || k == 12))
and that's equivalent to
if (![2,3,7,12].includes(k))
