In this final part of the course, we bring together all the concepts we have learnt about WebAssembly (Wasm) and grasp the true power it holds for web application development. WebAssembly creates the bridge we need to run performant, low-level languages in a secure and optimized way on web clients. Whether it's implementing computationally complex algorithms, working with graphics, or enabling better computational performance, Wasm takes web applications a notch higher.

The key points to remember about WebAssembly are:

1. WebAssembly is a binary instruction format built as a virtual compile target for the execution of high-level languages on the web, allowing code to run at near-native speed.

2. WebAssembly provides an efficient binary format that speeds up web applications by allowing them to run at near native speed. Its high-performance potential is fairly vital for performance-critical web applications.

3. It is safe and secure, running inside a sandboxed execution environment, providing better performance than JavaScript, especially for computational-heavy operations.

4. WebAssembly is language, platform, and hardware independent. It doesn't aim to replace JavaScript but to work alongside it, unlocking potent performance where it matters.

5. We can call WebAssembly functions from JavaScript, making WebAssembly a powerful tool to enhance JavaScript applications.

WebAssembly is increasingly being used in modern web development due to its performance advantages and support for languages other than JavaScript. As you integrate WebAssembly into your toolkit, you're adding the capability to create high-performance web applications with the languages you're used to in systems programming. While there's a steep learning curve, especially when interacting with JavaScript and handling memory manually, the performance gain is often worth the extra complexity for performance-critical applications.

This is the power of WebAssembly. It bridges the web and system programming, pushes the boundaries of what can be done in a browser, and opens the door to a multitude of possibilities.
