Learning goals

The reason why summarizes the source code of the tripartite library, is to read the source code to learn the original intention of the designer, including the design model, the principle of the computer architecture, not to deal with the interview, but the real understanding of the designer intention, imitate ideas, improve their coding level

    • What valuable or useful design lessons have you learned from this library?
  • The core of the source code should be handwritten
