Efficiently removes an element from an unordered array by swapping with the last element instead of splicing.
unordered-array-remove is a JavaScript library that efficiently removes elements from arrays when the order of elements is not important. It solves the performance problem of using Array.splice(), which shifts all subsequent elements, by swapping the target element with the last one and popping it off in constant time.
JavaScript developers working with large arrays or performance-sensitive applications where unordered array manipulations are common, such as game development or data processing.
It provides a significantly faster alternative to Array.splice() for unordered arrays, with a minimal API and no dependencies, making it ideal for performance-critical code.

It removes elements in O(1) time by swapping with the last array element, avoiding the O(n) shift of Array.splice(), as shown in the README's explanation.
The library is a single function with no external dependencies, keeping the bundle size minimal and reducing complexity.
With just one function call, it's easy to integrate and use, requiring only the array and index as inputs.
Specifically designed for performance-critical applications, such as game development or data processing with large, unordered arrays.
It inherently destroys the array order by swapping elements, making it unsuitable for any use case where element sequence matters, which the README explicitly states is a limitation.
Modifies the array directly, which can introduce side effects and break immutability patterns in modern JavaScript frameworks, requiring careful state management.
The README does not specify behavior for invalid indices, potentially leading to runtime errors without built-in safeguards, assuming developers handle validation.
