`Array.prototype.sort` sorts the elements of an array in place and returns the sorted array. The sorting is based on the UTF-16 code units of the elements by default, but can be customized with a comparison function. 

const arr = [3, 1, 2];
arr.sort();
console.log(arr); // [1, 2, 3]

`Array.prototype.sort` sorts the elements of an array in place and returns the sorted array. By default, it sorts elements as strings. A custom comparator function can be provided to sort elements in other ways. 

const arr = [3, 1, 2];
arr.sort();
console.log(arr); // [1, 2, 3]

`Array.prototype.sort` sorts the elements of an array in place and returns the sorted array. By default, elements are sorted as strings. A custom sorting function can be used to specify the sort order. 

const arr = [3, 1, 2];
arr.sort((a, b) => a - b);
console.log(arr); // [1, 2, 3]

`Array.prototype.sort` sorts the elements of an array in place and returns the sorted array. By default, the elements are sorted as strings. A custom sorting function can be provided for different sorting logic. 

const arr = [3, 1, 2];
arr.sort();
console.log(arr); // [1, 2, 3]

Use a min-heap of size K to keep track of the K largest elements. For each element, if it is larger than the smallest element in the heap, replace the smallest. For example, in [3, 2, 1, 5, 6, 4], the 2nd largest element is 5.

Binary search divides the search interval in half. Start with the middle element; if it matches the target, return it. Otherwise, adjust the search range to either the left or right half based on comparison. For example, searching for 4 in [1, 2, 3, 4, 5] returns index 3.

To sort data, select your range and go to the 'Data' tab. You can sort by one or multiple columns, either ascending or descending. For instance, sorting a list of products by price helps in quickly identifying the cheapest or most expensive items, streamlining decision-making.
