1, big factory recognition, hot job demand

Recently, visible hiring trends have become important in large factories, both in terms of the number of positions and salaries, which are on par with Or even slightly higher than Java. Go language has the characteristics of quick entry, library, fast operation, and so on. It is also a perfect balance between development efficiency and execution efficiency. It is the leader in the major programming languages.

The use of Go by companies is increasing year by year. Since its release in 2009, Go has been favored by many famous companies, including Tencent, B Station, Didi, Toutiao, Xiaomi, Qihoo 360, JINGdong and other star companies. The industry even once believed that Go had the potential to replace The King of Java. Go language is Google launched a new generation of development language, Go language from a famous family, you do not quickly get started, learn about it in advance.

2. Learning route & one-click acquisition of basic knowledge

The students who enter the Go language have different foundations, which can be divided into the following categories.

  • Students with no basic knowledge: they may be preparing for a career or just become interested in programming, and do not know much about computers, operating systems and networks.
  • Students with little or no programming experience: may be working in other technology-related jobs, may be proficient in scripting, but have less general knowledge and skills in programming.
  • Students with programming experience in other languages: May already be programmers or software engineers who can program proficiently in other programming languages, but don’t know much about Go.
  • Students with certain Go language programming experience: They have the Go language programming foundation and have written some Go language programs, but they are in urgent need of advancement but can’t see the path clearly.

Based on the above classification, I made a Go language learning path and basic knowledge map. No matter which category you fall into, you can follow this path to further your education.

3. Break down advanced knowledge points one by one

In addition to the basics, if you want to become an advanced Go language engineer, you need to complete the following knowledge points.

Data type:

  • Slice based on the underlying array;
  • A channel for transmitting data;
  • As a function of first-class citizens;
  • To achieve object-oriented structure;
  • Go language features – non-intrusive implementation of the interface.

In terms of grammar:

  • Asynchronous programming kill go statement;
  • The function’s last line of defense is the defer statement;
  • Switch statements that can make type judgments;
  • Multi channel operation tool SELECT statement;
  • The very featured exception handlers panic and recover.

The Go language comes with the program test suite, related concepts and tools include:

  • A dedicated testing code package;
  • And the powerful go test command.

Go language synchronization tools:

  • Classic mutex, read/write locks, conditional variables, and atomic operations;
  • Execute the helper sync.once, temporary object Pool sync.pool, sync.waitGroup, and context.context all at Once.

If you understand the above, you have mastered the essence of Go programming. After that, read up on the Go standard library and excellent third-party libraries. When you write software in Go, you’re comfortable with it.
