About

In Go, we can compare values using the equality and ordering operators. We have 6 of these operators:

Comparison	Operator
equal	==
not equal	!=
less	<
less or equal	<=
greater	>
greater or equal	>=

The result of a comparison is always a boolean value:

a := 3

a != 4 // true
a > 5  // false

Equality operators

The equality operators == and != check whether a value is equal to another or not, respectively. We can use the equality operators on the majority of types in Go. Here are some common examples:

2 == 3 // false, integer comparison

2.1 != 2.2 // true, float comparison 

"hello" == "hello" // true, string comparison

'a' != 'b' // true, rune/byte comparison

Ordering operators

Ordering operators check if one value is greater than (>), greater or equal to (>=), less than (<) and less or equal to (<=) to another value. This kind of comparison is available for numbers, bytes, runes and strings. When comparing strings, the dictionary order (also known as lexicographic order) is followed.

2 > 3 // false, integer comparison

1.2 < 1.3 // true, float comparison

'a' > 'b' // false, rune/byte comparison

"Hello" < "World" // true, string comparison
