Properties of an Error
Posted: Thu Feb 13, 2025 4:14 am
Smart programmers try to predict and cover these scenarios so that the user doesn't have to figure out a technical error message like "404" independently. Instead, they display a much more understandable message "The page could not be found."
Errors in JavaScript are objects that are displayed whenever a programming error occurs. These objects contain extensive information about the type of error, the statement that caused the error, and the stack trace when the error occurred. JavaScript also allows programmers to create custom errors to provide additional information when debugging problems.
Now that the definition of a JavaScript error is clear, it's time to get kuwait whatsapp number data into the details.
Errors in JavaScript carry certain standard and custom properties that help in understanding the cause and effects of the error. By default, errors in JavaScript contain three properties:
message : A string value carrying the error message
name : The type of error that occurred (we'll go into this in the next section)
stack : The stack trace of the code executed when the error occurred.
Additionally, errors can also carry properties such as columnNumber, lineNumber, fileName, etc., to better describe the error. However, these properties are not standard and may or may not be present in all error objects generated from your JavaScript application.
Understanding Stack Trace
A stack trace is the list of method calls that a program was in when an event such as an exception or warning occurs. Here's what an example stack trace with an exception looks like:
