Imagine a scenario where I have a function that specifically accepts non-negative numbers, but is given a negative argument.
If this were in Python, I would raise a ValueError. In Java, an IllegalArgumentException would be thrown. Is there a built-in exception that should be used in JavaScript for this situation, or is it best to simply return undefined?
One common dilemma developers face is whether to throw an exception or return a value.
I recommend checking out this helpful resource:
Remember, if your method can't fulfill its intended purpose, it's best to throw an error.
As mentioned on MDN, consider using
throw RangeError("x should be a non-negative number");Error class is preferable as it makes error handling in higher-level functions more straightforward.
