Consider the code block below: var windowObject Runtime ErrorsĪlso known as exceptions, these kind of errors occur when your program is executed, usually when it has been compiled or interpreted.
Usually, when a syntax error occurs in JavaScript, the rest of the code in other threads will get executed if they contain nothing that depends on the code containing the error. In the example above, the last line of code will cause a syntax error because it is missing a closing parenthesis. Check out the code block below: var x = 2 Also known as parsing errors, they occur at compilation time in traditional programming languages and interpretation time in JavaScript. They can be further subdivided into: Syntax Errors Programmer mistakes are errors made by the programmer when writing programs. For example, a program asking a user to enter a name, and it gets back an empty string. Actual problems are events that are not preventable by the programmer. Usually, JavaScript errors can be divided into two categories, actual problems, and programmer mistakes. When you are done, you won’t be scared of frequently implementing features such as the stack property as well as handling errors. My objective is to show you how JavaScript errors can be handled properly and avoided in your code.

It would be great if we all knew how to detect these errors, expose them and prevent them from happening again. In the long run, chances of your program running as expected reduce due to one thing ‒ errors.Įrrors in JavaScript could get complex at certain times and when that happens, programmers have no one to blame but themselves or the language itself.
Every programmer out there wants to write code that works.
