Recursion is the repeated application of a process. In JavaScript, recursion involves functions that call themselves repeatedly until they reach a base condition. The base condition breaks out of the recursion loop because otherwise the function would call itself indefinitely. Continue reading What is recursion and when is it useful?
Big O notation is used in Computer Science to describe the time complexity of an algorithm. The best algorithms will execute the fastest and have the simplest complexity. Algorithms don’t always perform the same and may vary based on the Continue reading What is Big O Notation?
If neither attribute is present, the script is downloaded and executed synchronously, and will halt parsing of the document until it has finished executing (default behavior). Scripts are downloaded and executed in the order they are encountered. The defer attribute downloads the Continue reading What are defer and async attributes on a Script tag?
In JavaScript classes, the methods are not bound by default. This means that their this context can be changed (in the case of an event handler, to the element that is listening to the event) and will not refer to the component Continue reading How do you ensure methods have the correct this context in React component classes?
When several components need to share the same data, then it is recommended to lift the shared state up to their closest common ancestor. For example, if two child components share the same data, it is recommended to move the Continue reading What does lifting state up in React mean?
