JavaScript Switch Statement

Switch Statement JavaScript

When using a switch statement like the video, it seems its just testing whether the case is true or not. I also found you can add multiple lines of cases to evaluate true as well. My question is can you test actual conditions, and what would the syntax look like? //testing multiple conditions switch(value){ case 'cat': case 'goat': case 'dog': console.log('Correct choice'); break; default: console.log('incorrect choice'); break; } //Can a switch statement test if value is > 3 or < 3? let value = 6;

switch (value) { case () break; }

Your first example (cat/goat/dog) looks correct and should work. But you cannot use "switch" for range comparisons. The nature of "switch" is that the cases represent exact matches with the provided value.

To implement range comparisons, try using an "if/else if/else" chain.

Thanks Steven! I normally use if or ternary statements myself, just wanted to make sure I wasn't missing out on a key concept in switch statements.
