Go Operators Explained

Go operators are symbols that perform specific actions on variables and values, categorized into arithmetic, comparison, logical, and bitwise groups. The compiler uses these operators to build expression trees, which it then optimizes or folds into constants during the SSA phase.

// Arithmetic: +, -, *, /, %
sum := 10 + 5

// Comparison: ==, !=, <, >, <=, >=
if sum > 12 {
    fmt.Println("Greater")
}

// Logical: &&, ||, !
if sum > 10 && sum < 20 {
    fmt.Println("InRange")
}

// Bitwise: &, |, ^, <<, >>, &^
mask := 0b1111
result := mask & 0b1010

Operators are the tools you use to calculate numbers, compare values, or combine logic in your code. Think of them like the buttons on a calculator or the switches in a circuit that tell the computer what to do with your data. The Go compiler analyzes these operations to make your program run faster by simplifying complex math before it even starts.
