In this article we are going to try how to secretly copy a JavaScript function to the clipboard. We use the copytext() method to secretly copy JavaScript function to the clipboard. These functions work on JavaScript console as well. To understand better let’s look into the examples one by one. Example Following is the example program we used copyText() method to copy text to clipboard using JavaScript function. Copy text ... Read More
To create table header in HTML, use the … tag. A table header tag is surrounded by the table row …. The tag is surrounded by the tag.

A bookmark is helpful when you want to remember the web page for future reference. You can access that bookmark at any time to view the web page again. We use HTML links to create bookmarks, so that we can jump to specific parts of a web page. Bookmarks can be useful if a web page is long. When we click on the link, the page will scroll down or up to the location with the bookmark specified on the web page. Syntax First, we should use the id attribute to create a bookmark text… Then, add a link ... Read More
We use the target attribute of the … tag, to change the target value of the link. The target attribute can be used to open any link in a new tab, current tab and so on. _blank − link will open in a new tab. _self − link will open in the current tab. _parent − link will open in a parent frame. _top − link will open in the top frame. Syntax Following is the syntax to change the target of a link in HTML. Link text… Example Following is the example program to change the ... Read More
The tree is a data structure that is comprised of nodes and edges. These entities are interconnected to each other to form a tree structure. Traversing a data structure means visiting each and every node in that structure and bringing out a sequence of values from that. There are three types of traversals namely, in-order (L→ Root→R ), pre-order(Root→L→R) and, post-order(L→ R → Root) In-order Traversal In the In-order Traversal, the left subtree is visited first, followed by the Root node and finally the right subtree. A binary tree will provide sorted key values in ascending order if it is ... Read More
Array is a linear data structure, which is able to store elements of different datatypes. Arrays are also defined as ordered collections. In array each of the value will be referred to as an element and those can be identified with index numbers. const array_name = [item1, item2, ...]; const movies = [Bahubali, RRR, KGF, Pushpa]; //Index values of above elements Bahubali – [0] RRR – [1] KGF – [2] Pushpa – [3] Loops is a programming element, there will be a sequence of instructions defined in the loop and it will continue to iterate till ...

An object is said to be an entity which has properties and types in it. Example, consider a Person as an object and it has properties like height, weight, age and salary. In the similar way JavaScript also have objects and their defined properties. An object in JavaScript is a complicated data type where it can store various data types in it. Let’s consider this example below const employee = { name : ‘Dhoni’, age : 41, height : 5.8, } Cloning an object using JavaScript In general, “Cloning” is ... Read More
Tree is a nonlinear data structure which has nodes and edges; where edges act as link between two nodes and nodes hold values in it. Traversal is a procedure where it will retrieve the data in every node of the tree and print them in a specified sequential order. There are three types of tree traversals which are mentioned below − In-order traversal − In-order technique will follow the path (Left → Root → Right). Pre-order traversal − Pre-order technique will follow the path (Root → Left → Right). Post-order traversal − Post-order technique will follow the path (Left ... Read More
A hemisphere refers to the exact half of a sphere. Means if we divide a sphere in two equal parts then we will get two hemispheres. Hemisphere is a three-dimensional geometrical shape which has one flat face. There are many practical examples of hemispheres. The earth divided into 2 equal parts results 2 hemispheres i.e. Northern hemisphere and Southern hemisphere. The area occupied by the outer surface of a three-dimensional object is called the surface area. Formula to calculate surface area of hemisphere − Mathematically it can be represented as $$\mathrm{Surface \:Area \:= \:2\pi\:r^2}$$ Mathematically it can be represented as ... Read More
