+# Instructions
+
+Implement various kinds of error handling and resource management.
+
+An important point of programming is how to handle errors and close resources even if errors occur.
+
+This exercise requires you to handle various errors.

+# Error Handling
+
+In this exercise, you will implement a function called `processString` that processes a given input string with proper error handling.
+
+You will learn how to:
+
+- Check input types and throw errors for invalid inputs.
+- Throw errors for specific cases (e.g., empty strings).
+- Return the uppercase version of the string if it is valid.
+- Handle and catch errors using a try..catch block
+
+
+Implement the processString function using a `try…catch` block.
+
+Inside the `try` block:
+- If the input is not a string, throw a `TypeError`.
+- If the input is an empty string, return `null`.
+- If input length is greater than 100, or less than 10, throw a `RangeError`
+- If input contains a mix of letters and numbers, throw a `SyntaxError`.
+- Otherwise, return the input in `uppercase`.
+
+*Don't forget to attach appropriate error messages then you throw! An informative and well structured error message can save you hours of debugging.*
+
+Inside the `catch` block:
+- log the error's message using `console.log`
+- `throw` the `error` so it can be tested for its type.
