To match any single character in the given set with JavaScript RegExp, use the [aeiou] metacharacter.Example           JavaScript Regular Expression                        var myStr = "Welcome to our website!";          var reg = /[we]/g;          var match = myStr.match(reg);                    document.write(match);          

In this tutorial, we will understand two approaches to display the document's title using JavaScript. Using document.title Property One of the most used methods in JavaScript to access an HTML document’s title is using a document.title property. In the following example, you will learn to get access to the title. After accessing the title in JavaScript, you can manipulate it and change the way it is displayed on a website. Syntax Here you can see how with the use onClick method, we can set the innerHTML of a paragraph within the document. The document.title is used to grab the title, ... Read More

To match any single character outside the given set with JavaScript RegExp, use the [^aeiou] metacharacter.Example           JavaScript Regular Expression                        var myStr = "Welcome!";          var reg = /[^lc]/g;          var match = myStr.match(reg);                   document.write(match);          

To match any string with p at the beginning of it with JavaScript RegExp, use the ^p Quantifier −Example           JavaScript Regular Expression                        var myStr = "Welcome to our website. We Learners!";          var reg = /^We/g;          var match = myStr.match(reg);                    document.write(match);          

To match any string containing a sequence of at least two p’s with JavaScript RegExp, use the p{2,} Quantifier.Example           JavaScript Regular Expression                        var myStr = "Welcome 1, 10, 100, 1000";          var reg = /\d{2,}/g;          var match = myStr.match(reg);          document.write(match);          

To match any string with p at the end of it with JavaScript RegExp, use the p$ Quantifier.Example           JavaScript Regular Expression                        var myStr = "Welcome to our website! Welcome";          var reg = /me$/g;          var match = myStr.match(reg);                    document.write(match);          

In this tutorial, we will convert Boolean to Number in JavaScript. The Boolean is the variable's data type, which is supported by JavaScript like the other programming languages. The Boolean data type contains only two values, true and false. In some cases, programmers must convert the true or false value to the number. For example, using the strict equality operator to compare the Boolean value with the number variable. Here, using different operators, we have three methods to convert the Boolean to a number. Using the Number() Function In JavaScript, the Number() function is useful to convert any variable to ... Read More
