Arrays

1. Chunk

let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
console.log(arr.chunk(2)); // Output: [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ], [ 7, 8 ], [ 9, 10 ] ]
console.log(arr.chunk(3)); // Output: [ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 7, 8, 9 ], [ 10 ] ]

let arr = ["rock", "plane", "apple", "rise", "banana", "red"];
 
console.log(arr.dropIf((item) => {
   return item.startsWith("r"); // Output: [ 'plane', 'apple', 'banana' ]
}))

7. First

let arr = ["blue", "green", "red", "yellow"]
console.log(arr.first()); // Output: blue
