JS Basic concepts that some people miss
- Promises in JavaScript provide a cleaner and more readable alternative to callbacks, preventing callback hell.
- Promises have stages like Pending, Fulfilled, and Rejected, making asynchronous code execution easier.
- Promise method examples include Promise.all, Promise.allSettled, Promise.race, and Promise.any.
- Throttling limits the execution of a function to prevent it from running more than once in a specified interval.
- Debouncing delays function execution until there is a period of inactivity, useful for scenarios like search inputs.
- Event Propagation includes Event Capturing, Target, and Event Bubbling phases in the DOM.
- Concurrency in JavaScript involves handling multiple processes or threads executing simultaneously to avoid data conflicts.
- DB Isolation Levels such as Read Uncommitted, Read Committed, Repeatable Read, and Serializable help maintain data consistency in Concurrent operations.
- JS Strict Mode enforces rules to make the code more error-free by disallowing certain behaviors like using undefined for 'this' in the global context.
- Prototype in JS refers to a blueprint containing shared properties and methods for instances created from a constructor function.
