Why you should care
Creating a new Error without actually throwing it is useless and is probably due to a mistake.How we detect
CAST Highlight counts one occurrence each time 'throw' is not used before the 'new' operator used to instanciate an error class (Error | EvalError | InternalError | RangeError | ReferenceError | SyntaxError | TypeError | URIError). Bad Codeif (x < 0) {
new Error("x must be nonnegative");
}
if (x < 0) {
throw new Error("x must be nonnegative");
}
