Why you should care

[/vc_column_text][vc_column_text]Creating a new Error without actually throwing it is useless and is probably due to a mistake.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]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 Code 

if (x < 0) {
  new Error("x must be nonnegative");
}

Good Code 

if (x < 0) {
  throw new Error("x must be nonnegative");
}
