As a beginner in JavaScript, it can be overwhelming to decide which topics to focus on first. After mastering the basics of the language, it is highly recommended that you dive into learning about array methods and promises. These are powerful and essential tools for any JavaScript developer and will greatly enhance your ability to write efficient and effective code.
Array Methods
JavaScript arrays are a fundamental data structure in the language and their methods allow you to perform a wide range of operations on the data they contain. From sorting and filtering data to transforming it, the array methods are an indispensable tool in your JavaScript toolbox.
Some of the most commonly used array methods include sort(), filter(), map(), and reduce(). Each of these methods serves a specific purpose, but when used together, they can create powerful combinations for working with your data.

Promises
Promises are a fundamental aspect of JavaScript and are used to handle asynchronous code. This is important because JavaScript is a single-threaded language and you need to be able to perform tasks that take time to complete (such as making an API call) without blocking the rest of the code from executing.
Promises provide a way to represent the eventual outcome of an asynchronous operation and they provide a means of handling errors and results. This makes your code more maintainable, readable and efficient.

Array methods and promises are two of the most important topics for beginner JavaScript developers to master. By learning how to use them, you will greatly enhance your ability to write effective and efficient code and you will be well on your way to becoming a proficient JavaScript developer.
