Error objects are thrown when runtime errors occur In my case the root cause was async related (during a codebase refactor) An asynchronous function that builds the object to which the not a function function belongs was not awaited, and the subsequent attempt to invoke the function throws the error, example below: Errors and exceptions are inevitable in application development As programmers, it is our responsibility to handle these errors gracefully so that the user experience of the application is not compromised Handling errors correctly also helps programmers debug and understand what caused them so they can deal with them
Javascript has been a popular programming language for over three decades. The javascript language error handling error handling, try.catch custom errors, extending error ctrl + ← ctrl + → When executing javascript code, different errors can occur Errors can be coding errors made by the programmer, errors due to wrong input, and other unforeseeable things. Javascript error reference below, you'll find a list of errors which are thrown by javascript These errors can be a helpful debugging aid, but the reported problem isn't always immediately clear
Each error is an object based upon the error object, and has a name and a message. The error.iserror() static method determines whether the passed value is an error.
