JavaScript has steadily entered all the most popular areas of life. No site can exist without this programming language, and a mobile application can now also be developed using only JavaScript (for example, on React Native), server development on Node.js, Telegram bots, and even desktop applications (Electron) can be written using only JavaScript.
However, you should not be too confident. Sometimes very simple things, at first glance can be very complicated if you dig into them. To write high-quality applications, you need to understand the basic concepts in this language, and only after that should you move on to frameworks. The developer’s task is to cultivate the culture of a software engineer and not become a hostage to one or two frameworks.
In this article, we will talk about the possibilities of JavaScript development services and what a reliable partner for developing this technology should be able to do.
What is JavaScript for?
First, let’s figure out why JavaScript is needed at all. In web applications, HTML is responsible for the page layout. The layout of the content and the interface’s appearance are described using CSS, and JavaScript is responsible for the interactivity and functionality of this interface. Here are examples of tasks that JavaScript solves:
- User interaction. Pop-up windows with a field for entering mail or other data and notifications about using cookies.
- HTML data processing. JavaScript helps fill in the required fields in forms, validate literal and numeric values, and manage HTML elements on the page. For example, in the Tilda landing page builder, you can drag and drop blocks and change fonts, text colors, background colors, and other values on click.
- Animation. These are moving objects on the page and buttons, and a carousel in the gallery or smooth scrolling of the page. For example, Pinterest created an endless feed effect using JavaScript.
- Mathematical calculations. With the help of JavaScript scripts, calculators are implemented on websites, for example, calculating the amount of an order in an online store basket.
Today, no technology in the web development industry could push JavaScript out of its leadership position. It’s just so convenient and successful that it makes no sense to create something new. Only some add-ons can compete with classic JS. Here, the code is, of course, easy to use, but before starting work, it always becomes pure JavaScript. The great advantage of JavaScript is its relevance, which never passes but only continues to develop.
What should a reliable JavaScript partner know?
If you want to work with a reliable JavaScript development provider, you first need to find out what a good partner can do and how to choose one. The roles of JavaScript experts are divided according to the duties they perform. JavaScript was originally used to design the interface of websites and web applications.
But today, it is not limited only to the external interface but is also used internally. In addition, hybrid mobile applications, interactive games, smartwatch applications, and more are created using JavaScript frameworks.
The primary focus of front-end developers revolves around crafting visually appealing and user-friendly websites. They make the site interactive by adding a graphical interface so that users can easily interact with the products and services on the site. Front-end JavaScript frameworks such as React and Vue are used to create interactive user interfaces, component-based applications, and large single-page applications, respectively.
Backend developers step in when accessing server data and making the site responsive. They create the server side of the project. Back-end development mainly consists of the server, the application, and the database. This person should know server-side JavaScript languages such as Node.js, Express.js, and more.
In addition, they should be aware of various databases, such as SQL and MongoDB. Knowing basic JavaScript frameworks like Express, Next.js, and Koa helps them build a more robust foundation and APIs.
Outsourcing JavaScript development vs. hiring a full-time specialist
Since knowledge of JavaScript, at least at a basic level, is mandatory for all web programmers, JavaScript specialists work in completely different types of organizations, including large corporations and government bodies, small and medium-sized companies, as well as solo freelancers. But the experience of these developers will be very different, and hiring a staff specialist can become a lengthy procedure.
By working with a Javascript development company, you can create any web application, from simple to complex. In this case, ordering this service from an IT service company can be much more profitable, regardless of whether the project requires a responsive user interface with an attractive design or needs to enter the mobile application market. Outsourcing companies’ staff contains specialists of various levels and can form effective teams to quickly solve problems.
Creating online stores without the use of JavaScript tools is impossible today. Because JavaScript has no serious competitors, it is used in most work on launching sites for online stores. The creation and filling of websites are necessary for a simplified perception of the resource by the visitor.
Embedding animations, graphics, tooltips, and recommendations on pages — all this, with the right approach, greatly simplifies the process of navigating the site. It is clear that every online store aims to attract customers, so having an informative and interactive website increases the likelihood of buying a service or product.
JavaScript website programming increases the likelihood of success because there is simply no other suitable toolkit for this task, which is not foreseen shortly. Writing code to launch an online store on your own is difficult without experience, so you should entrust this task to professional programmers.
