golang initialize map code example
Example 1: create map golang
//map in go is a built in type implementaiton of has table
//create a empty map
myMap := make(map[string]string)
//insert key-value pair in map
myMap["key"] = "value"
//read from map
value, ok := myMap["key"]
//delete from map
delete(myMap, "key")
Example 2: initialize map in golang
// By default maps in Go behaves like a default dictionary in python
m := make(map[string]int)
m["Dio"] = 3
m["Jonathan"] = 1
Example 3: go get from map
var id string
var ok bool
if x, found := res["strID"]; found {
if id, ok = x.(string); !ok {
//do whatever you want to handle errors - this means this wasn't a string
}
} else {
//handle error - the map didn't contain this key
}
