– 1. The message: This is the string value that conveys the error message.
– 2. The name explains the type of error you’ve encountered.
– 3. The stack: This mentions the stack trace of the code executed when the error happened.
1. The Uncaught Range Error
Different scenarios can create an uncaught range error in Google Chrome. The browser’s maximum call stack size is exceeded, and execution is blocked because the memory is exhausted.
The immediate solution is to reduce the number of function calls or limit the number of variables. The alternative uses a tracer debugger that tracks the program’s status and locates the function prompting the error.
2. The Uncaught TypeError: Cannot Set Property
When the value is different from the expected one, you face a TypeError. It’s called “Uncaught” because the error isn’t caught in the try-catch block.
It becomes undefined if you declare a variable without assigning it a value. The result is the error – Uncaught TypeError Cannot set property of undefined. The solution is to initialize the reference by assigning a value before you access the reference’s properties.
3. The Uncaught TypeError: Cannot Read Property
You’ll encounter many such errors where a property is read, or a function is called on an undefined variable.
The solution lies in providing an initial default value to the undefined state container.
4.TypeError: ‘undefined’ Is Not An Object
This error appears in Safari when a property is read/function is called on an undefined variable. The problem is fixed when you initialize your variables properly, and the property does not remain undefined when the function is called.
5. TypeError: Null Is Not An Object
You’ll see such errors occurring on Safari when the object whose property or method is being accessed is showing as null and not as undefined.
6. TypeError: Cannot Read Property ‘length.’
In the older versions of Chrome, this happens when you read the length of a null or undefined object, and it frequently occurs when handling lists. In the updated versions of Chrome, the error might appear as “Uncaught TypeError: Cannot read properties of undefined.” The solution is to make sure the object you are accessing exists and is not set to null.
7. TypeError:‘undefined’ Is Not A Function
This error occurs in Google Chrome when the method you invoke doesn’t exist in the script or the method can’t be referenced in the calling contact. The right approach is to check the line of code triggering the error and fix the issue.
It makes a big difference if you equip yourself with the right tools and deploy proper techniques to isolate errors and prevent application malfunction.
