ConstReturns the module defined with key.
Returns every defined module.
Loads every module not yet loaded, one at a time while the host is idle.
Loads nothing while offline, when the connection asks to save data, or on a 2g connection, and
with onlyWhenFast nothing unless the browser reports a fast connection.
Stops as soon as that changes, so call it again when the connection recovers; modules that
already loaded are skipped. Modules defined with prefetch: false are never loaded ahead of
use. A module that fails to load is left for its first use to retry.
Removes module, so it is no longer loaded ahead of use. A module defined since under the same
key is kept.
The modules defined with defineLazyModule.
