Implementing Rakam analytics for a web game (Friday Night Funkin style)

Hi dev team,
I am currently developing a web-based rhythm game project inspired by Friday Night Funkin. I want to integrate Rakam to track user engagement metrics, specifically "Song Completion" and "Combo Rates".
Does the current JavaScript SDK support high-frequency custom events for this type of HTML5 game efficiently? Or should I batch the events before sending?
Thanks for any advice!
