Performance
Deno supports user timing Level 3 (see: https://w3c.github.io/user-timing) which is not widely supported yet in other runtimes. These types are here so that these features are still available when using the Deno namespace in conjunction with other type libs, like dom
.
Methods
Stores a timestamp with the associated name (a "mark").
Stores the DOMHighResTimeStamp
