Event bubbling is the order in which event handlers are called when one element is nested inside a second element, and both elements have registered a listener for the same event (a click, for example). With bubbling, the event is first captured and handled by the innermost element and then ... Read More

The unshift method adds the element at the zeroeth index and shifts the values at consecutive indexes up, then returns the length of the array.The push() method adds the element at end to an array and returns that element. This method changes the length of the array.Examplelet fruits = ['apple', ... Read More

The shift method removes the element at the zeroeth index and shifts the values at consecutive indexes down, then returns the removed value. If the length property is 0, undefined is returned.The pop() method removes the last element from an array and returns that element. This method changes the length ... Read More

The basic difference between slice and splice is −splice() changes the original array on which it is called and returns the removed item(s) in an array as a new array object.slice() doesn't change the original array and also returns the array sliced.Example// splice changes the array let arr = [1, ...

Shallow copy and deep copy are language agnostic. Shallow copies duplicate as little as possible. A shallow copy of a collection is a copy of the collection structure, not the elements. With a shallow copy, two collections now share the individual elements.Examplelet innerObj = {    a: 'b',    c: ... Read More

The radix sort algorithm distributes integers into buckets based on a number's significant digit or value (the radix). The radix is based on the number system of the values of the arrays. Let us look at how it can be implemented −Examplefunction radixSort(arr) {    // Find the max number ... Read More
