Data types

Essential Question: What data types does JavaScript use and how are they different from the other programming languages that I learned?

Mastery Objectives:

• SWBAT create variables using the different data types in JavaScript.

Do Now: Write a JavaScript program to calculate days left until next New Year's Eve.

Directions: Create a program in repl.it to demonstrate each type of data type. Call the program, Data Types.

1. On line 1 write your age to the console. This is a number.

2. On line 2 write your name to the console. This is a string.

To declare variables, write var then the name of the variable. For example, var Name = "Ms. Moylan"
