Go Operator Precedence Table

Go operator precedence determines the order of evaluation for expressions, with multiplication and shifts binding tighter than addition and comparisons.

Go does not have a single built-in operator precedence table in its standard library, but the language specification defines a strict hierarchy where multiplication, division, and shifts bind tighter than addition and comparisons. You can verify the binding order of any expression by wrapping sub-expressions in parentheses to force evaluation order, as shown below.

// Precedence: * > + > ==
// 10 + 2 * 3 evaluates to 16, not 36
result := 10 + 2 * 3

// Use parentheses to override default precedence
// (10 + 2) * 3 evaluates to 36
result := (10 + 2) * 3

The full precedence order from highest to lowest is: * / % << >> & &^, then + - | ^, then == != < <= > >=, then &&, and finally ||.

Operator precedence is the rulebook that tells the Go compiler which math or logic operations to do first when you write a complex line of code. Think of it like the order of operations in school math, where multiplication happens before addition unless you use parentheses to change the plan. You use this knowledge to write shorter code without accidentally calculating the wrong result.
