How to iterate over all key-value pairs in a map in Go?

To iterate over all key-value pairs in a map in Go, you can use a for range loop. The for range loop with a map iterates over each key-value pair in an arbitrary order.

Here is an example of iterating over all key-value pairs in a map:

myMap := map[string]string{
    "key1": "value1",
    "key2": "value2",
    "key3": "value3",
}

for key, value := range myMap {
    fmt.Println("Key:", key, "Value:", value)
}

In this example, the for range loop iterates over each key-value pair in the myMap variable. The key and value variables are assigned to each key-value pair in each iteration. You can perform any desired operations on the key and value variables inside the loop.
