How do I compare maps in Go?

In Go language, you are allowed to compare two maps with each other using DeepEqual() function provided by the reflect package. This function returns true if both the maps satisfy the following conditions: Both maps are nil or non-nil. Both maps have the same length.

How do you compare two maps with values?

We can compare if values contained in the map objects are the same or not by converting all map values to set using values() method and then compare values with the equals() method of the set.

How do you compare in Go?

In Go language, the string is an immutable chain of arbitrary bytes encoded with UTF-8 encoding. You are allowed to compare strings with each other using two different ways: 1. Using comparison operators: Go strings support comparison operators, i.e, ==, !=

How do you compare two structs in Go?

In Go language, you are allowed to compare two structures if they are of the same type and contain the same fields values with the help of == operator or DeeplyEqual() Method.

How do I compare two interfaces in Go?

Two interface values are equal if they have identical dynamic types and equal dynamic values or if both have value nil. A value x of non-interface type X and a value t of interface type T are comparable when values of type X are comparable and X implements T.

How do I iterate a map in Golang?

How to iterate over a Golang map in sorted order

  1. Create a slice.
  2. Store keys to the slice.
  3. Sort the slice by keys.
  4. Iterate over the map by the sorted slice.

Which of the following options can be used to compare two maps?

The correct answer is to use equals . String.

How do you compare two structures?

To find out if they are the same object, compare pointers to the two structs for equality. If you want to find out in general if they have the same value you have to do a deep comparison. This involves comparing all the members. If the members are pointers to other structs you need to recurse into those structs too.

How do you compare two structured objects?

In the Object Oriented World, generally, all Objects are unique to each other. So, how I could compare two objects? With the Equatable protocol you can implement the static func == . Here you can define how two object of the same class could be equal when you use the operator == .

What is interface {} Golang?

interface{} means you can put value of any type, including your own custom type. All types in Go satisfy an empty interface ( interface{} is an empty interface). In your example, Msg field can have value of any type.
