Goroutines are lighter threads Threads are more efficient than in Java Co operative grammar go func() { //... }() Once the code in the main goroutine is executed, the current Go program will be terminated, regardless of whether other goroutines are already running. Let the master goroutine wait for other goroutines: for i := 0; i < 10; i+ ...

GO Language Function Programming-Closure concept GO function closure Functional Programming for Fibonacci Sequences concept The main support of go language for function programming is mainly embodied in closure functions. Functions are first-class citizens: parameters, variables, and return val ...

IPFS itself does not use many new technologies, most of which are existing technologies and ideas, but it cannot be said that there is no innovation, similar to Bitcoin. dht Ideas: KadDHT's node addressing and content addressing are isomorphic. On the basis of KAD calculating logical distance based on XOR, the specific physical distance such as ...

Two of the most attractive things about Go, besides goroutine, that is, channel, I've been wondering how select ion actually works. As in my previous article, some irrelevant code is omitted directly 1. Overview of structure 1.1. hchan This is the structure of channel. type hchan struct { qcount uint // Total data in queues da ...

About a year ago, there was such a problem:There are N routines executed concurrently in the program, which will write data to a channel with size n. The N routines have high concurrency and load, so they don't want to be stuck when writing data, so they use this code. if len(c) < n { c <- something // Write in } The original meaning ...

Zero Value Characteristic Some operations of uninitialized map s are legal: var testMap map[int]int size := len(testMap) // size is 0 _, present := testMap[0] // present is false non := testMap[123] // non is 0, won't case panic testMap[1] = non // panic: assignment to entry in nil map Only write operations ...
