features, the most important that it supports all of the
structured programming syntax in C except for scoping. It does
not allow C-like block-level scoping because it has its own
support block-level scoping with the keyword “let”. Also like
statements; a strong dissimilarity between the two is that
out these semicolons to terminate statements and the program
will automatically place them afterward.
types with values instead of variables, allowing variables to
be bound to numbers, for instance, and then strings without
samples; object names are string keys, and programmers can
add, change, or remove properties and their values at run time
as well as evaluate functions for statements provided as
themselves are objects, having properties and the ability to
move around and interact like other objects.
Functions within other functions are inner functions, created
when the programmers call up their outer functions. Variables
of that outer function for that instance continue to exist for
as long as their inner functions exist, until that session is
functions were to return they would still have access to their
outer function’s variables.

This makes it possible to reproduce class-based features in
constructors as well as their typical activities. Programmers
can prefix a function call with “new”, which creates a new
object and binds it with its local “this” keyword for that
single invocation, and the constructor’s prototype properties
decide which object to use for this new object’s interior

methods. When this happens, the function’s local “this”
keyword binds to that specific object for that one invocation.
