Debouncing is a programming technique used to limit the rate at which a function is executed, especially in response to events.
Debouncing ensures that a function is not called too frequently, which can improve performance.
Commonly used in scenarios like window resizing, scrolling, or input field changes.
Example: In a search input, debouncing can delay the API call until the user stops typing for a specified time.

The event loop is a fundamental concept in JavaScript that manages asynchronous operations and execution of code.
JavaScript is single-threaded, meaning it can execute one command at a time.
The event loop allows JavaScript to perform non-blocking operations by using a call stack and a message queue.
When an asynchronous operation (like a setTimeout or a network request) is initiated, it is sent to the Web APIs.
Once the o...
call, apply, and bind are methods to set the 'this' context in JavaScript functions, with different invocation styles.

apply: Similar to call, but arguments are provided as an array. Example: func.apply(thisArg, [arg1, arg2]);
bind: Returns a new function with a specified 'this' value, allow...

They enable polymorphism, allowing objects to be treated as instances of their ...

Make sure you do no cutting and are clear about the approach you'd be following.
Running median of an input stream is the median value of the numbers seen so far in a continuous stream of data.
Maintain two heaps - a max heap for the lower half of the numbers and a min heap for the upper half.
Keep the number of elements in the two heaps balanced or differ by at most 1.
If the total number of elements is odd, the median is the root of the max heap. If even, it is the average of the roots of the two he...
