A jump statement is one, which forces the flow of execution to jump unconditionally to another location in the script.

Jump statements in JavaScript are used to terminate iteration statements.

A function call causes execution to go unconditionally to a new location (the beginning of the function's script source text block - its body) but a function call is not strictly a jump statement because the flow of control returns eventually to the line forllowing the function call.

A return statement is considered to be a jump statement.
