Home / JavaScript / JavaScript Errors – Understanding and Correcting
A short note about errors before we proceed to the next session.
When you are learning a new programming language it takes time to understand its syntax. Your code might have a few bugs; it’s okay as long as you know how to correct them.
JavaScript beginners mainly make three kinds of errors
They might try to call a variable that is not yet defined.
Solution: Remember to always initialize all variables you expect to use in the script.
Forgetting the starting or ending quote or parenthesis as in a method or function.
Solution: Place the opening and ending parenthesis or quotes together, then write the code/text between them.
Using a property or method that does not belong to an object, for example, using document.alert() instead of window.alert().
Solution: You don’t have to learn each and every object’s properties and methods at the very start… you’ll get the hang of it all gradually.
