When using loops, it is important to remember to include a condition that will end the loop. This is done by using the “break” keyword. Without this, the loop will continue to run indefinitely, which can cause errors and slow down the page. Additionally, it is important to use the “continue” keyword to skip over certain items in the loop. This can be useful when you only want to perform certain actions on certain items.
Events allow us to track user interactions with a website. Event listeners are the mechanism that allows us to declare code to be executed when an event occurs. Event listeners are associated with an element on the page and will run code when they detect an event like a button click or a mouse movement. Listeners allow us to quickly respond to user actions on a page.
Utilizing Different Libraries and Frameworks for Web Development
Modern web browsers allow developers to utilize features such as WebRTC, WebSockets and Service Workers in order to create full-fledged interactive websites and applications. Features such as these allow us to send data between devices or create real-time streaming communications over an HTML page. With the correct implementation of these features, developers can work faster with less resources.
