In JavaScript, it is considered a best practice to use certain patterns to detect errors instead of solely relying on try-catch blocks. One easy way to do this is by using TypeError:
if (typeof foo !== "number") {
console.log("That ain't a number!");
return;
}
Similar patterns can be used for detecting ReferenceError and RangeError as well.
However, the challenge arises when trying to test for a URIError before utilizing encodeURI() or decodeURI() without resorting to try-catch blocks.
(An acceptable response might be that it is not possible).
