![]() ![]() You can also use JavaScript to perform and develop browser-based games.Įxample 3 JavaScript Program to Format the Date With Expected Output You can also implement JavaScript to develop modest web servers and extend using back-end infrastructure with Node.js. Various organizations like JavaScript code libraries practice using Node.js, a JavaScript runtime environment developed JavaScript V8 engine.For developing front-end-based UIs here, you can include other various client technologies, such as Angular, React Native.JavaScript frameworks are groups of plenty of JavaScript code libraries that help developers and write the code as per certain requirements.Developers can use multiple JavaScript frameworks for developing web and mobile-based applications.Performing audio and video on a web page.Performing a timer and defining count-down on a website.Zooming in/zooming out feature on an image.Slide by a carousel of images on the home webpage.Change the color of a button after hovering the mouse hovers over it.Show/hide more data or user information using with the click of a button.JavaScript provides users to interact with web pages as per the below examples as per the requirements.Defining interactive response and performance to web pages.You can also use Javascript for implementing hardware controls. JavaScript is essentially handled and used for web-based applications. JavaScript enhances the user experience of the web page by transforming it from a static page to an interactive one. It is all the features and behavior designs developed by Javascript. You can take a simple authentic example of JavaScript that you can use and see in the search box on the Amazon web portal. You can use it for developing web pages with its more interactive and user-friendly benefits. ![]() We saw how easy it is to create a user interface interactive using HTML, CSS, and JavaScript, also saw how to import our web assets from CDNs, and got the chance to make our application able to convert speech to text successfully.JavaScript is a text-based programming language that you can use from server-side and client-side in your. In this article, we built a speech-to-text application with Javascript. When this happens, our application will inform the user via the instruction box. We also created the onspeechend event handler triggered when there is no input from the microphone, and the application is in an idle state. If any error occurs during this process, our application will inform the user via the instruction box. We also created the onerror event handler triggered when an error occurs while transcribing the speech. If you click the Start button, you will see that it will automatically convert whatever you speak into text and fill the transcribed text inside the textbox. In this function, we will fetch the transcript of the speech given to us by the event.results variable, then update our previous content variable and textarea with the new results. This event is triggered when the recognition API has successfully converted speech from the user’s microphone to text, and the data is made available via the event.results variable. Next, we will write code for the onresult event handler. Here, we programmed our application to inform the user that voice recognition is on and converts speech to text. The onstart event handler is triggered when the recognition API starts and has microphone access. They are onstart, onspeechend, onerror, and onresult. We also added a couple of event handlers to the recognition object to bring our application to life. When you press the button, your browser will request permission to use your microphone, as shown in the image below. When this happens, the recognition API is begun and will listen for input from the user. ![]() We created an event handler triggered whenever the user clicks on the Start button to start recognizing. Thus, we are making the API continuously listen for input from the user’s microphone. We then set the continuous variable of the recognition object to true. ![]() We are initializing it to an empty string because we have not converted anything yet. We also created a content variable that keeps track of text the application has converted and displayed in the textarea from the HTML file. In the code above, we invoked the Web Speech Recognition API and initialized an instance stored in the recognition variable.Īfter this, we made references to our #textbox and #instructions elements we defined in the HTML using JQuery to control them from our code.
