The first point is that you need to learn a lot to become a
software developer. It is not possible to explain in detail all the technical skills you may need to master as devops, but I will list some of the most critical technical skills. Choosing a programming language is the most important. Front-end development is the most popular development position today. Senior front-end development engineers are very lacking in the enterprise. To become a
front-end development engineer, the first step should be to learn HTML / CSS / JavaScript, which is the foundation and the foundation. JavaScript is the foundation of the foundation and is deeply rooted. Many novice programmers will try to learn several programming languages at one time or before their first job, in order to be prepared. Although I think you should eventually learn more than one programming language, I do not recommend doing this in advance, because it will only cause confusion and will distract you from other skills you need to learn. On the contrary, I suggest that you should study in depth and focus on learning the ins and outs of a single programming language so that you can have full confidence in writing code in this coding language.
How to construct code
What do I mean by building code?
I mean well-written, clear, and understandable code that doesn't require a lot of comments, because the code itself is universal.
Many
software developers have gone through their entire careers without
learning this skill, which is unfortunate because it is the main way for me and many others to judge the skills and capabilities of software developers.
A good code structure shows the focus on the process, not just to complete the work.
Building code is actually an art part of software development, but it is also important because you and your colleagues must use the code and it will take more time to maintain existing code instead of writing new code.
Object-oriented design
This is controversial, especially if the programming language you are learning is not object-oriented, but there are a large number of software development worlds that will think in terms of object-oriented design, so you need to make sure you understand it.
Object-oriented design is a method of decomposing complex programming into separate classes or objects (instances of classes), which encapsulates functions and has specific roles and responsibilities.
In software development, we always try to manage complexity. Thinking from an object perspective can help us do this, because it allows us to define and design a complex system from a bunch of interactive components, rather than trying to solve the entire complexity as a whole.
There are a large number of functional programming languages in the current programming world, but the most popular languages and patterns you find in software development are still heavily influenced by object-oriented design and analysis. You should understand what classes are, the different types of inheritance-when to use them-and understand terms like polymorphism and encapsulation.
Algorithms and data structures
If you go to a traditional college and want to get a degree in computer science, then this is a big test site. Algorithms are common methods for solving various computer science / programming problems. For example, there are several common algorithms for procedural sequencing. Each sorting algorithm has a series of different attributes regarding speed, memory size requirements, and the ideal type of data. There are many such algorithms in the field of computer science, and it is also important to understand how to change these algorithms to solve the difficult problems you may encounter when you solve real-world programming problems. Usually, being good at these algorithms allows one developer to solve problems that may take another developer a few days to figure out within an hour. Unless you are familiar with and good at algorithms, you do n’t even know that there are elegant solutions out there. Therefore, just for this reason, I think this is also a valuable skill worth mastering. The same is true for data structures and can be used in conjunction with algorithms. There are several
software developers that should be familiar with data structures, including: array or vector linked list stack queue tree hash collection. By mastering data structures and algorithms, you can easily and elegantly solve many difficult programming problems. When I started programming, I was terrible at data structures and algorithms because I mainly learned by myself. I never realized the value of them. Soon, as I encountered some problems that I didn't know how to solve, I found these skills very useful in the real world of programming, and the solution was quite simple-and interesting. In fact, I think this is one of the most interesting areas of software development. Solving difficult problems and using data structures and algorithms to develop a clean and elegant solution really makes sense. Learning these things is a challenge, but it is well worth it. This is one of the skills that allows you to surpass many peers. Most
software developers are not good at this field. If you want to pass an interview with a big company like Microsoft or Google, then you must master this skill set.
Development platform and related technologies
You should have some experience and at least master a development platform and related technologies or frameworks. What do I mean by platform? Ok, usually it means operating system (OS), but it also applies to other abstractions that can act like operating systems. For example, you can be a Mac developer or a Windows developer focused on the Mac or Windows operating system, or you can be a web developer focused on a specific web platform. I will not discuss exactly what the platform is-different people will have different views-but here I want to define the specific environment for the platform to develop for you, it has its own ecosystem and particularity. Furthermore, this is another technical skill that I think the choice is not so important, as long as you choose one. Enterprises usually hire developers to develop software for specific platforms or technologies. As an iOS developer, it will be easier for you to find a job if you are specialized in that particular platform. This means being familiar with the platform itself, as well as development tools, idiomatic patterns, and the general framework that most programmers will use when developing for that platform. You may think that the choice of programming language determines the platform, but in reality this is rarely the case. Take C # as an example. If you are a C # developer, you can use this programming language to write code for Windows, Mac, iOS, Android, Linux, and even embedded systems. So, don't just choose the language; choose the platform.
Frame or stack
In addition to learning specific programming languages and platforms, I highly recommend learning the framework, or better yet, the complete development stack that matches it.
What is a framework? What is a stack?
A framework is a series of libraries used to develop code on a specific platform or multiple platforms. It can usually make programming tasks on the platform easier.
Look at this C # example. Most C # developers use the .NET framework to write C # applications. The .NET framework includes many libraries and classes that allow C # developers to work at a higher level of abstraction, because whenever he wants to do something, there is no need to completely reinvent the wheel. For example, part of the .NET framework also contains code for processing images. It is extremely difficult to write such code from scratch, so the framework greatly helps C # developers to write code that needs to process images in some way.
The stack is a bit different. A stack is a set of technologies, usually including a framework, and often used together to create a complete application. For example, there is a common stack called MEAN. It represents MongoDB, Express.js, AngularJS, and Node.js. MongoDB is a database technology.
Express.js is a Node.js framework for creating web applications.
AngularJS is a front-end JavaScript framework for creating user interfaces for web applications.
Finally, Node.js is a runtime environment for developing web-based applications using JavaScript.
It is not important to understand all of these things-unless you plan to become a MEAN developer-it is important to understand that if you know all these technologies and frameworks, then you can develop a complete web application. Stacks make it easier to create applications because they provide a common paradigm that many developers use to develop applications, so knowledge can be easily shared, and you can also determine which specific skill marts can work together of. The learning stack is really valuable because it means that you have all the necessary skills to develop a complete application. Many companies that use specific stacks to develop applications prefer to hire
software developers who are familiar with that type of stack and can work immediately.
