*Python - Installation of PyPi*
https://youtu.be/PNDN402anTk

The Python Package Index, abbreviated as PyPI and also known as the Cheese Shop (a reference to the Monty Python's Flying Circus sketch "Cheese Shop"),is the official third-party software repository for Python. It is analogous to CPAN, the repository for Perl. Some package managers, including pip, use PyPI as the default source for packages and their dependencies. Over 235,000 Python packages can be accessed through PyPI.

PyPI primarily hosts Python packages in the form of archives called sdists (source distributions) or precompiled "wheels."

PyPI is an index that allows users to search for packages by keywords or by filters against their metadata, such as free software license or compatibility with POSIX.[11] A single entry on PyPI is able to store, aside from just a package and its metadata, previous releases of the package, precompiled wheels (e.g. containing DLLs on Windows), as well as different forms for different operating systems and Python versions.

*JavaScript - Basics of Reserved Words*

In any programming language, a reserved word or a reserved identifier is a word that cannot be used as an identifier, such as the name of a variable, function, or label. Thus, it is reserved and cannot be used for defining any of these. This is a syntactic definition, and a reserved word may have no meaning.
