Introduction to Node.js

Capture User Input

• capture command-line arguments - using: the process object, the .slice() method (i.e. array slicing)
• intro to JavaScript ES6
• protect data with const

  Print Dynamic Output

• ES6 arrow function expressions (used to perform one action in the function with implicit return, can omit curly braces; used to perform more than one action in the function, need to use more traditional function syntax & keep the curly braces to wrap it.)
• print arguments one at a time.
• using let for variables that need to change over time
• using const for variables that should never be reassigned.
• cleaner loops using new array method called .forEach()
• • USING ARROW FUNCTION = AVOID USING function keyword, parentheses around the function parameter, & the curly braces used to wrap a function, as we're only performing one action in the function.

To recap, we learned the following:

• That Node.js is a runtime environment popular for building applications that run outside of the browser

• How to create and execute an application build with Node.js

• What JavaScript ES6 (ECMAScript 6) is, how to use some of its features, and how they can benefit us
