Destructuring Arrays

  • Destructuring allows unpacking values from arrays or properties from objects into distinct variables.
  • Instead of accessing elements by index, destructuring enables pulling specific items with names directly.
  • Array destructuring simplifies assigning array elements to variables in a single line of code.
  • Assignment with destructuring involves declaring variables inside square brackets and matching them to array elements based on positions.
  • Skipping elements in array destructuring is possible using a comma as a placeholder for the skipped element.
  • The rest operator (...) gathers remaining elements into a new array, and it must be the last element in the destructuring pattern.
  • Default values can be provided in array destructuring to handle missing elements in the array.
  • Destructuring offers a concise way to swap values of variables without a temporary variable.
  • In React, array destructuring is commonly used with hooks like useState for concise code and clear variable naming.
