PRESENTATION OUTLINE
Variables—
Both programming languages use variables. Though, in JavaScript, they always begin with ”var,” whilst in Python, a statement before the variable name is not needed.

Truthiness—
Both languages use “true/false,” though in JavaScript, all letters are lowercase and in Python, the first letters are capitalized: “True/False.”

Nothingness—
JavaScript has two values that represent nothingness: ”undefined” and “null.” Python has only one: “None.”

Numbers—
Numbers are used in both programming languages; sometimes as variables, and other times, in equations.

Function Declarations—
In JavaScript, function declarations are also expressions and can be anonymous; the function name can be omitted. This allows a few interesting uses that Python does not have, because in Python, functions cannot be anonymous, and are not expressions, so they cannot be defined and used on the same line.

Strings—
When using Python, strings can contain letters, numbers, and symbols; they must be enclosed within quotation marks, and when using an apostrophe, you must put a blackslash before, so the rest of the string isn't messed up. In JavaScript, you cannot use only quotation marks, because then the computer will assume that is a variable. Instead, you must put it within the “text” statement and include it within parenthesis, which is then followed by the x and y position of the text.

Lengths—
In JavaScript, the length (of a string) would be typed out as: str.length, whilst in Python, it would be written as: len(“message here”)

Arrays/Lists—
JavaScript has a built-in array type and uses square brackets, and Python uses square brackets in their “list” functions.

Bracket Types—
In JavaScript, there are three brackets used, which are { }, ( ), and [ ]. The curly brackets are used to define the start and end of the function. They also separate code into blocks within the function. The [ ] brackets are used for arrays, and the standard parenthesis, ( ), is used for when parameters are either sent or received. And in Python, curly brackets create either dictionaries or sets, whilst square, [ ], brackets create lists. And like in JavaScript, ( ) are just the basic bracket type.
