Does Strict Mode Change How JavaScript Function Expressions Behave? Are you curious about how strict mode influences the behavior of function expressions in JavaScript? In this detailed video, we'll explore the effects of enabling strict mode on your JavaScript code, specifically focusing on function expressions. We'll start by explaining what strict mode is and how to activate it within your scripts or individual functions. You'll learn how strict mode enforces stricter rules that can help you catch errors early and write more reliable code.

We'll discuss how strict mode impacts variable declarations, the handling of "this" inside functions, and syntax restrictions like disallowing the "with" statement. Additionally, you'll see how these changes apply equally to both function declarations and function expressions, regardless of how they are defined or called. This understanding is essential for developers aiming to write cleaner, safer, and more predictable JavaScript code.

Whether you're new to JavaScript or looking to improve your coding practices, understanding the role of strict mode in function expressions is a key step. We'll also share practical tips on how to use strict mode effectively in your projects to prevent common mistakes and enhance your development process.
