30. Async/Await
Maximiliano discusses how async/await is just a syntax sugar on top of the promises API and does not change how promises work. He also demonstrates how to use async/await to consume promises and make asynchronous code look more synchronous and error handling with try/catch.

31. Promises: allSettled, any, & finally
Maximiliano discusses the advantages of using promises over callbacks. He also mentions the concept of "promisifying" data, which involves returning a promise instead of a synchronous value, making it easier to switch to asynchronous data sources in the future.

34. Proxies & Reflect API
Maximiliano explains that a proxy is a design pattern that allows you to intercept and modify object behavior, and the Reflect API provides methods for working with objects dynamically. He also demonstrates how to create a proxy for an object and set traps for specific actions, such as getting a property value.

35. Symbol
Maximiliano discusses symbols, a new type introduced in ECMAScript 6 that are unique and immutable primitive values. Symbols are often used to create unique property keys for objects and can be used as identifiers or keys in various scenarios.

36. Error Cause & Hashbang Grammar
Maximiliano discusses chaining exceptions, where one error is caused by another error. He also explains the hashbang grammar, which is a syntax used in Unix-based systems to specify the interpreter for a script, particularly useful for Node.js scripts.
