Implement Throttle with Configurable Leading and Trailing

Problem Statement

A production-grade throttle should support both leading and trailing edge execution. This provides immediate response AND ensures the final state is captured. Implement a fully configurable throttle.

Requirements

Implement a throttle(func, wait, options) function where:

• leading (boolean, default: true) - execute on leading edge
• trailing (boolean, default: true) - execute on trailing edge
• Both can be true simultaneously (default Lodash behavior)
• At least one must be true (validate this)

Example Usage

Behavior Matrix

Leading	Trailing	First Call	End of Window
true	true	Executes	Executes (if queued)
true	false	Executes	Nothing
false	true	Queued	Executes
false	false	Invalid - throw error

Follow-up Questions

1. How does this compare to Lodash's throttle implementation?
2. What edge cases exist when both options are true?
