short hand for chaining logical operators in javascript?

Question

Is there a better way to write the following conditional in javascript?

if ( value == 1 || value == 16 || value == -500 || value == 42.42 || value == \'somet         


        

Answer 1

You could extend the array object:

Array.prototype.contains = function(obj) {
  var i = this.length;
  while (i--) {
    if (this[i] == obj) {
      return true;
    }
  }
  return false;
}

Then if you store all those values in an array you could do something like MyValues.contains(value)
