📖 Rule Details

This rule aims to enforce the use of exponentiation (**) operator instead of other calculations.

The exponentiation operator (**) provides several advantages over alternatives:

• Readability: More concise and mathematically intuitive
• Performance: Often better optimized by JavaScript engines
• Consistency: Standard ES2016+ syntax for exponentiation
• Type Safety: Better behavior with edge cases compared to Math.pow

This rule was inspired by ESLint Core's prefer-exponentiation-operator, but additionally detects multiplication with the same operands.
