There is one final bit of syntax we want to introduce you to before we get you to play with some examples. The ternary or conditional operator is a small bit of syntax that tests a condition and returns one value/expression if it is true, and another if it is false — this can be useful in some situations, and can take up a lot less code than an if...else block if you have two choices that are chosen between via a true/false condition.
