any way to chain == and || operands [duplicate]

Question

I have a situation where I have to make a check like this:

if foo == a || foo == b || foo == c {
  //do stuff
}

is there any way to chain these operands into something smaller like IDK foo == a||b||c

Answer 1

Try this:

if [a, b, c].contains(foo) {
   //do stuff
}
