What are the pros and cons of using JavaScript as a full-stack web development language?
由人工智能和领英社区提供技术支持
Full-stack web development is the process of creating web applications that involve both the front-end and the back-end. The front-end is the part of the web application that interacts with the user, such as the user interface, the layout, the graphics, and the functionality. The back-end is the part of the web application that handles the data, the logic, the security, and the communication with other services. A full-stack web developer is someone who can work on both the front-end and the back-end of a web application.

A butcher, a baker, a candle stick maker. A magician of Accessibility. Master Dev of all data. Artistic Freelancing fool. Languages and foundations of our trade that we give up countless hours to master, until the next update, the next version. And we must remain vigilant on all fronts, lest the pirate bots come calling, or the very foundations of Open Source and Proprietary Apps are exploited or depreciated. That the Browsers remain compatible and content readable and pleasant in all view ports. That the site loads swiftly, that the Google God's are pleased. Yes, we serve proudly as the guardians of the internets.
One of the main benefits of using JavaScript for full-stack web development is that you can use the same language for both the front-end and the back-end. This can simplify your development process, reduce the learning curve, and increase your productivity. You can also reuse code, libraries, and frameworks across the front-end and the back-end, which can save time and resources. Additionally, JavaScript is a widely used and supported language, which means that you can find a lot of resources, documentation, tutorials, and community support online. JavaScript is also a flexible and dynamic language, which allows you to create interactive and responsive web applications.

I completely agree with this, I've chosen tech stacks for large scale projects for this easy. I commonly use Vue/React to Node/Express to MongoDB. Javascript from start to finish. I feel it made it easy to bounce back and forth... I found one small down side... which I'll cover in the next section
One of the main drawbacks of using JavaScript for full-stack web development is that you have to deal with the complexity and diversity of the JavaScript ecosystem. There are many different tools, frameworks, libraries, and standards that you have to choose from, which can be overwhelming and confusing. You also have to keep up with the fast-changing and evolving nature of JavaScript, which can introduce compatibility and security issues. Furthermore, JavaScript is not a perfect language, and it has some quirks and limitations that can cause bugs and errors. For example, JavaScript is not strongly typed, which means that it can produce unexpected results when working with different data types. JavaScript is also single-threaded, which means that it can block the execution of other tasks when performing intensive operations.

Too many frameworks? I don't think this is valid point as all languages have far more frameworks than you are going to want to use. This point could be made about ALL tech stacks. Javascript is not strongly typed or the prefect language. This is a feature not a bug. Trying to strongly type javascript causes more problems than it solves in my opinion. But If you are into strongly typed languages... why pick Javascript at all? JavaScript is single-threaded. This is true, but Node is multi-threaded, so if can be multi threaded. Design issue. The issue not covered here I've found, in when using Javascript for your DB, it's more verbose to do things than it is in SQL... SQL is really streamlined.

With modern JavaScript and runtime environments, it’s possible to write non-blocking code. Being single threaded isn’t a real limitation for most use cases. JS supports writing asynchronous code, which is good for I/O intensive tasks and can work on a single thread. There are also options for using multiple threads for CPU-bound tasks on both client and server. For multiple threads, the browser has Web Workers and Node has the worker_threads module. Some criticize JS’s threading as “not real multi-threading”, but for most use cases it doesn’t make a difference. One benefit of the way threading is implemented in JS environments is that it’s much harder to create concurrency problems, like race conditions, than with ”real multi-threading”.
Full-stack JavaScript web development can be facilitated by a number of tools and frameworks. Node.js, Express, React, and MongoDB are some of the most popular and widely used ones. Node.js is a runtime environment that runs JavaScript on the server-side, and is based on the Chrome V8 engine which is both fast and efficient. Express is a web framework for Node.js that provides a simple and elegant way to create web applications, being lightweight and modular. React is a front-end library for creating user interfaces, using a component-based architecture and virtual DOM for improved performance. Finally, MongoDB is a document-based database that stores data in JSON-like format, integrating well with Node.js and Express while offering features such as indexing, aggregation, and schema validation.

I think React.js is the most popular JavaScript library. Node.js, Express.js, MongoDB, etc. This stack is easy to learn. Nowadays, Next.js is gaining popularity and is good for everything. Just do/learn whatever you want to do.
If you're interested in full-stack JavaScript web development, there are several steps you can take to get started. First, brush up on the basics of JavaScript, such as syntax, data types, operators, control structures, functions, objects, arrays, and events. You should also become familiar with the fundamentals of web development, like HTML, CSS, DOM, HTTP, REST, JSON, and AJAX. After that, you'll need to choose a code editor or an IDE that meets your preferences and needs. Node.js and npm (Node Package Manager) should be installed on your machine so that you can run JavaScript on the server-side and manage your dependencies. Additionally, select a web framework for Node.js such as Express, Koa, Hapi or Sails to create web applications easily and efficiently. For constructing user interfaces, opt for a front-end library or framework like React, Angular, Vue or Svelte. Finally decide on a database for storing and retrieving data like MongoDB, PostgreSQL, MySQL or Firebase to manage your data and perform CRUD operations. To enhance your full-stack JavaScript web development experience even further you can use tools and frameworks such as webpack, babel, eslint jest mocha chai and more. Additionally build projects to demonstrate your full-stack JavaScript web development skills like a blog a chat app a todo list a weather app or an e-commerce site. Finally stay up to date by reading books blogs articles podcasts videos courses and tutorials online as well as joining online communities and forums where you can ask questions share ideas and get feedback from other developers.

To get started, just jump in there and give a try. There is no replacement for actual experience. Maybe pick a code kata found on the internet and turn that into a small full stack javascript project. I have a few examples my blog, but I hate self promotion.

Start with full-stack JavaScript. 1. HTML for 1 week: focus on basic syntax and tags. 2. CSS for 1 week with the same focus. 3. JavaScript for 3 weeks, building some projects. 4. After learning, you can jump into any JavaScript UI library. Nowadays, the most popular one is React.JS. It is easy to learn, so you can start with it. Spend 3 to 4 weeks learning, create 2 to 3 projects such as a to-do list, restaurant menu, etc. 5. Now it's time to move to the backend. Start with Node.js. Learn some fundamental concepts and then proceed to Express.JS and for databases you can learn MongoDB, MySQL, etc. This will take around 3, 4 weeks. 6. Build APIs, try to use Postman. 7. Now it's time to implement your backend code into the frontend. Go ahead.
