Performance Optimization

Lodash includes performance optimizations for frequently used operations. For example:

• _.memoize(func, [resolver]): Creates a memoized version of a function. Memoization caches the results of function calls, improving performance when the function is called with the same arguments multiple times.
  • Example:

const expensiveFunction = (num) => { // Simulate an expensive operation return num * 2; }; const memoizedFunction = _.memoize(expensiveFunction);

• _.debounce(func, [wait=0], [options]): Delays invoking a function until after a specified wait time has elapsed since the last time it was invoked. Useful for handling events like resizing or scrolling.
  • Example:

const handleResize = _.debounce(() => { console.log('Resized!'); }, 200); window.addEventListener('resize', handleResize);
