javascript - JS Short for if (a == b || a == c)

Question

I'm searching for a short way to write this:

    if ( variable == 1 || variable == 2 || variable == 6)

I tried

    if (variable == 1 || 2 ||?6)

but it doesn't seem to work. Is there an easy way to do this?

Answer 1

You can do it by putting your possible values in an array and using Array.indexOf:

if ([1,2,6].indexOf(variable) != -1)
