What happens when a JavaScript error occurs?
What happens when a JavaScript error occurs?
This is a question that many developers ask, and the answer can vary depending on the situation. Generally speaking, however, there are a few things that will happen when a JavaScript error occurs.
For one, an error message will be displayed in the browser. This message will give the developer information about what went wrong, and will often include a line number and a description of the error.
In addition, the code that caused the error will likely not run. This means that the page will likely be displayed in a different way than it was intended, and certain features may not be working.
Finally, depending on the error, the developer may be able to correct it. In some cases, however, the error may be too severe to correct, and the page will need to be fixed manually.
