JavaScript Pro-Level and One-Liners for Engineering Rigor

Writing clean, concise JavaScript is a hallmark of a senior engineer. One-liners are not just about saving space; they are about expressive, functional code that is easy to reason about.

### 1. Array Deduplication
`const unique = […new Set(array)];`

### 2. Deep Clone
`const clone = (obj) => JSON.parse(JSON.stringify(obj));` (Note: Use structuredClone for modern browsers).

### 3. Shuffle an Array
`const shuffled = arr.sort(() => Math.random() – 0.5);`

### 4. Flatten Nested Arrays
`const flat = arr.flat(Infinity);`

### Engineering Rigor at VDPL
While one-liners are powerful, we prioritize readability and maintainability. Our internal code reviews ensure that every piece of JavaScript pushed to production in our Delhi NCR hub meets the highest standards of engineering rigor.
