1. Variables
Here we go

2. How does a computer remember things?
To make our programs remember things, we store information as “variables”
Work the same way as variables in math go
x = 5;
x = 20;
bestName = “Guzy”;

3. Computers have memory?
Each variable stores its value in MEMORY, in a reserved spot of a specific size
Different variable types require different memory sizes
So we must DECLARE a variable to reserve the spot before we can use it to store information

4. Variable types
INTEGER- Integer numbers, positive AND negative. But no decimals.
STRING- Stores words, names, even novelty license plates like “1WOOO1”
CHAR- Characters, single letters, or number, or symbols.
FLOAT or DOUBLE- Decimals, take up a huge amount of space compared to integers
BOOLEAN- True or False values (more on this another time)

5. Special quirk of javascript
Is what we call “Loosely typed”, we make variables without stating what type they are
You can declare a variable, and give it any type later on
To declare a variable:
var myVar;
var myVar = “Guzy”;
var myVar = new String;

6. TO DO Declare 6 variables at the top
Make 3 of each: INTEGER, STRING in the INIT section of the code, using names and made up grades
Display on the screen using the fillText command the following:
Each name with the corresponding grade, 1 line per person
Calculate the average
