Throttle Function

Challenge summary

Implement a leading-only JavaScript throttle that limits a high-frequency callback to one execution per interval. The challenge makes the timing contract explicit so ignored calls and interval boundaries are predictable.

What you'll practice

• Execute the first call in each interval immediately.
• Ignore additional calls while the current interval remains active.
• Preserve the original arguments and calling context.
• Allow a new call once the interval boundary has passed.
