JavaScript evolution: From Lodash and Underscore to vanilla

Modern JavaScript has reduced the need for utility libraries like Lodash and Underscore. Many tasks can now be accomplished with built-in methods. Array operations use Array.prototype methods, while object manipulation utilizes spread operators and JSON utilities. Even complex operations like throttling and debouncing can be implemented in vanilla JavaScript. Developers can thus reduce bundle size and improve language understanding by writing their own utility functions instead of relying on external libraries.
