Golang : Of hash table and hash map
A short note for myself. Was looking to build a knowledge base consisting of a keyword or key string and then lookup for the nearest possible string answer.
This kind situation calls for a hash table and was looking for hash table equivalent in Golang and ....just found out that Golang's map is equivalent to other programming languages hash map or hash table! #facepalm to myself.
In general, a hash map is useful as it offers fast lookups, adds, and deletes. In Golang, the built-in map type has these properties.
NOTE : Map types are reference types, like pointers or slices, and so the value of m above is nil; it doesn't point to an initialized map. A nil map behaves like an empty map when reading, but attempts to write to a nil map will cause a runtime panic; don't do that. To initialize a map, use the built in make function:
m = make(map[string]int)
