Focus Point Recently, the father of Node Ryan Dahl released a new open source project Deno, from the official introduction, it can be considered as the next generation node (its goal is not to replace node. js), using the Go language instead of C + + rewrite the cross-platform underlying kernel driver, the upper layer still uses the V8 engine, and ultimately provide a A secure TypeScript runtime.

Using the web framework itself is completely unnecessary, but when you have new requirements, you can make smarter choices about where to migrate from. # # The difference between migrating from another language to GoGo and other languages is the language details. When migrating from Python to Ruby or from PHP to Javascript, you'll find the same difference. Go is no exception.
