JavaScript offers powerful features like higher order functions, method chaining, strict equality, and closures.Higher-order functions are functions that return other functions or objects, enabling dynamic behavior and function composition.Method chaining allows calling multiple methods in a single line, improving readability and reducing boilerplate code.JavaScript has abstract (==) and strict (===) equality operators; it's recommended to use strict equality to avoid unexpected results.Closures in JavaScript allow inner functions to access variables from outer functions even after the outer functions have finished executing.
