Array Destructuring
Array destructuring unpacks sequential array values directly into distinct local variables.
01 How It Works
Think of sliding items sequentially out of slots into separate containers.
Variables match sequential index positions in the source array structure.
example.js
const rgb = [255, 128, 0];
const [red, green, blue] = rgb;1. Target a source array.
2. Wrap target variable names inside square brackets [].
3. Extract positional values.
02 Practical Example
Here is how you might see this concept applied in real-world code:
practical.js
const coords = [10.5, 20.1];
const [lat, lng] = coords;Key Takeaway
Array destructuring provides concise syntax for unpacking ordered list items.
