Understanding Operator Precedence

What is Operator Precedence?

Operator precedence determines the order in which operators are evaluated in an expression. Operators with higher precedence are evaluated before operators with lower precedence.

Associativity

  • • Left-to-right: Operations of equal precedence are evaluated from left to right
  • • Right-to-left: Operations of equal precedence are evaluated from right to left

Example (JavaScript)

a + b * c → a + (b * c) because * has higher precedence than +

Tips

  • • Use parentheses to make your intentions clear
  • • Don't rely solely on precedence for complex expressions
  • • Different languages may have different precedence rules
  • • When in doubt, use parentheses to group operations explicitly
