Intro to Code Foundations

Variables

100

A named location where a piece of data is stored

Variable

200

When we explicitly write a value into code rather than using a variable to reference it

Hardcoding

300

The value of statement below: 

myCookbook = 'The Joy of Cooking'
 
yourCookbook = 'How to Cook Everything'
 
statement = 'My favorite cookbook is ' + myCookbook 

'My favorite cookbook is The Joy of Cooking'

What does will the variable myNumber hold at the end of the following code snippet?

myNumber = 1;

myNumber = myNumber + 1;

myNumber = myNumber * 2;

500

The value of the variable finalString at the end of the following code snippet

string1 = "Hello ";

string2 = "world!";

finalString = string1 + string2;

"Hello world!"

Datatypes

100

A single character

Char

200

A binary true or false value

Boolean

300

A whole number

Integer

400

A series of characters

String

500

A numerical value with a decimal point

Float or double

Functions

100

A shorthand for a set of instructions for the computer to execute

Function

200

Data that is given back by a particular function

Return value

300

Placeholders in a function definition that represent values that will be given to the function at the site of the function call

Parameters

400

Variables that are passed in to a function in the () at the site of the function call.

ex. the string passed in to 

console.log("Hello World!");

Arguments

500

This is what it's called when we actually run our function

(Function) calling

Loops

100

Used to execute a block of code repeatedly as long as a certain condition is met

Loops

200

A loop that will execute at least once

Do while loop

300

A loop that executes pending a single conditional statement

While loop

400

A loop that repeats over each item in a collection

For each loop

500

A loop that takes an initialization, conditional, and iteration expression

For loop

Potpourri

100

When you name a variable but don't assign a value to it

Declaration

200

The name for the expression in the for loop that initializes the counter variable

The initialization expression

300

(True/false) when one variable is assigned to another variable (e.g. variable1 = variable2), they actually point to different locations in memory.

False, they will point to the same location in memory

400

What a lone "=" is called in programming

The assignment operator

(Hint: there are only variations on for- and while-type loops)
