To ensure that you're able to test out the examples in a browser, you need to make sure that there's a global WebAssembly object available. To prevent any issues related to browser compatibility, I recommend that you have either Google Chrome or Mozilla Firefox installed for development. If you had either of these browsers installed beforehand, there's a very good chance that your browser is already valid. For the sake of being thorough, we will still cover the validation process. In this section, I will review the steps you can take to ensure that your browser supports WebAssembly.
