5 JavaScript Features I Wish I Had Learned Earlier

Short summary

A beginner-friendly listicle covering five JavaScript features: optional chaining, nullish coalescing, destructuring, spread operator, and array methods. Each feature gets a brief before/after code example. The content is thin and covers well-known ES6+ features without depth.

• •Destructuring and spread operator for cleaner code
• •Array methods like filter and map for expressive iteration
