Which language uses !== instead of != ?

  PHP. The !== checks for equality and for type. For example, it is true in PHP that 0 == false, but it is also true that 0 !== false.

    Also Javascript: https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Operators/Comparison_Operators https://developer.mozilla.org/en/Core_JavaScript_1.5_Referen...

      Correct.

    But given that now and then are both of type Temporal, he should still go for !=.

      There are coding style guides that advocate using the strict operators everywhere it makes sense. http://javascript.crockford.com/code.html http://javascript.crockford.com/code.html

        Ah, sorry, I read it as "equality of type".

  It's strict not equal in JavaScript. 'Returns true if the operands are not equal and/or not of the same type.' . '==' and '!=' are coercive in JavaScript -- as in: 5 == "5" -> true 5 != "5" -> false 5 === "5" -> false 5 !== "5" -> true
