✏️ Practice: Using MDN Documentation JavaScript

Goal: In the lesson on using MDN documentation, we learned:

  • Documentation is an umbrella term that includes tutorials, guides, references, and links to other resources and tools.
  • MDN has references for JavaScript, HTML, and CSS among other topics.
  • MDN has a search feature on the website, and MDN can also be accessed via Google searches.
  • MDN reference pages have built-in consoles that we can use to test out code.

Warm Up​

  • What does the official syntax for naming a method look like?
  • Why is it important to be comfortable working with documentation and researching online?
  • What is the good and the bad of following "rabbit holes"?

Practice Navigating MDN​

For folks who are working through this practice in pairs, switch off who's driving and observing in between each of the following prompts.

  1. Starting on the MDN homepage, navigate to the JavaScript Reference homepage.
  2. Find the MDN reference page for the method to lower case a string by searching on Google or using MDN's search feature.
  3. Find the MDN reference page for the String.prototype.charAt() method by searching on Google or using MDN's search feature.
  4. Search for the reference page for String.prototype.slice(). Read about how this method works and use MDN's built-in console to try out this method.
  5. Search for the reference page for String.prototype.subString(). Read about how this method works and use MDN's built-in console to try out this method.
