problem. gc supports cross-platform compilation. For example, we can build a Windows executable on a Linux OS, and vice versa. Programs written in go language mostly compile very fast. Compilation time is short warm-up duration (so great deployment experience) Some other compiled languages, such as C/C++/Rust may also have these three advantages (and they may have their respective advantages compared to Go) "JavaScript": 1995, }, LangCategory{false, true}: map[string]int{ "Go": 2009, "Rust": 2010, }, LangCategory{false, false}: map[string]int{ "C": 1972, }, } can be simplified
