You are given a portion of a Go programming language code snippet. Your task is to complete the code by determining the missing part.

The provided code is a part of a function that checks whether two variables, `that` and `this`, are equal. If they are equal, the function returns `true`; otherwise, it returns `false`.

To complete the code, you need to assign a value to the variable `that1` and implement the appropriate logic to determine the equality of `this` and `that1`.

Your task is to fill in the missing part of the code snippet.

Complete the code by replacing the `_____` with the missing code.

```go
func checkEquality(this, that interface{}) bool {
	that1 := _____
	
	// Missing code

	return _____
}
```

Sure, let's assume that you want to check if two strings are equal. Here's how you can complete the code:

```go
func checkEquality(this, that interface{}) bool {
	that1, ok := that.(string)
	if !ok {
		return false
	}

	return this == that1
}
```

In this code, `type assertion` (`type - interface`) is used to convert the `that` interface to a `string`. `ok` is a boolean variable that indicates whether the conversion was successful or not. If the conversion is successful, the function compares the string values using the `==` operator. If the conversion fails, the function returns `false`.

Sure, I can help with that. In Go, you can use type assertion to check if two interface{} variables hold the same value. Here's how you can complete your function:

```go
func checkEquality(this, that interface{}) bool {
	that1, ok := that.(typeOfThis) // replace 'typeOfThis' with the actual type of 'this'

	if !ok {
		return false
	}

	return this == that1
}
```

In this code, `that1, ok := that.(typeOfThis)` is a type assertion. It asserts that the interface{} value `that` is not nil and that the concrete value stored in `that` is of the specified type `typeOfThis`. If the assertion succeeds, `that1` will hold the underlying concrete value stored in `that`. If the assertion fails, `ok` will be false.

Please replace `typeOfThis` with the actual type of `this`. If the type is not known at compile time, you might need to handle different types separately or use reflection, which is more complex.
