Variables Here we go

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”;

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

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)

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;

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
