Intersection Observer, Dates & Intl

Enjoy dozens of new tutorials on modern JavaScript APIs…

• The IntersectionObserver object can be used to observe an element and run a callback function when it enters or leaves the viewport (or another element).
• The Intl object is the parent object for a handful of objects that comprise the Internationalization API. They can format numbers, dates, and more into localized strings.
• The Date object provides methods for getting and setting details about the moment in time.

And if you missed them, there were also a handful of great questions in the Slack community last week…

• “How do you pass parameters and user details from one page to another in a web app?”
• “How do you detect when a user reaches the top or bottom of a page and add more elements?”
• A practical example of Web Components.
• “How do you customize the messages displayed with native form validation?”
• “How do you assign variables to the global scope from an ES module?”
