Declare and use a variable with a number data type in JavaScript.
Write code using JavaScript number properties.
Write code using JavaScript number methods.
In this beginning-level project you will work with the number data type, and with properties and methods that apply to numbers. You will use Notepad++ to write JavaScript code and the Chrome browser to view your results. For a JavaScript programmer, understanding how to deal with variables that contain numbers is a prerequisite for any kind of number processing – even something as simple as accepting a number from a prompt() method and using it in a calculation. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:
Write JavaScript code to declare a variable and then assign a number value to that variable.
Use the Number() method to convert a value in a string variable to a number.
Write JavaScript code to convert a number variable into a string variable using the toString() method.
Use methods to check whether the value of a variable is an integer, or not a number at all.
Experiment with number properties in JavaScript code.
