Javascript Programming Tutorials, Guides & Best Practices

• apply: Intercepts function calls.

  const handler = {
      apply(target, thisArg, argumentsList) {
          console.log(`Function called with arguments: ${argumentsList}`);
          return target(...argumentsList);
      }
  };

  const sum = (a, b) => a + b;
  const proxy = new Proxy(sum, handler);
  console.log(proxy(1, 2)); // Output: Function called with arguments: 1,2 3

Lodash is one of the most popular JavaScript utility libraries, offering a wide range of functions for common programming tasks such as working with arrays, objects, and strings.
