For a person who wants to become a JavaScript developer, there is a question that may always bother him: Should he remember all the grammatical rules, functions and APIs of JavaScript? This question is very common because JavaScript is a large and complex language that contains a variety of different features and usages. However, the answer to this question is not that simple.

First of all, it is impossible to remember all the syntax rules, functions and APIs of JavaScript. JavaScript has syntax and content that have become historical, as well as very new and experimental syntax and content. It is an impossible task to completely master all aspects of JavaScript. Even if you try to master everything, it is extremely time-consuming and labor-intensive.

Secondly, JavaScript is a dynamic language, so its behavior may change depending on the context in which it is executed. This also means that you don’t need to know all the syntax rules and functions of JavaScript, just the ones you need. In your work, you may find that there are some frequently used patterns and features, while others are rarely used, or even never used. So you can master these in your own practice rather than trying to memorize everything.

Nevertheless, it is very important to remember some basic things, especially the core syntax of JavaScript, such as variable declarations, function definitions, conditional statements, and loops. Before you start writing any JavaScript code, you should master these basic syntaxes. In addition, you also need to spend time learning some common JavaScript APIs, which include DOM manipulation, AJAX, and the basics of JavaScript object-oriented programming.

At the same time, memorizing all the syntax and API does not mean mastering JavaScript. A good JavaScript developer should not just write some code, but understand how to use the language wisely to solve complex problems. This requires skills such as knowing how to use design patterns, optimization algorithms, and writing maintainable code.

In short, it is not necessary to remember all JavaScript. You need to understand the basic syntax and common APIs of JavaScript, but you do not need to master all language features and APIs. You need to practice these in your daily work, and later on you will find that you have mastered the things you need. At the same time, to become a good JavaScript developer, you need to spend time learning some advanced skills, such as design patterns, code optimization, and maintainability.
