• A piece of HTML specification infrastructure which can be used for running scripts independent of the main JavaScript execution environment, while not requiring a particular implementation model. Worklets are similar to web workers but are thread-agnostic; they are able to have multiple duplicate instances of the global scope created; they do not use an event-based API; they have a reduced API surface on the global scope; and they have a lifetime for their global object which is defined by other specifications. ← HTML
