JavaScript Vs. jQuery: Which to learn first?

, , Leave a comment

JavaScript being a largely well-known client-side scripting language, it does not require any foundation. Apart from the fact that it is utilized as a component of web browsers, it also manages the web browsers themselves, puts into force user interaction, gives the user customized content and enhances asynchronous communication. Therefore, quite a number of web developers make use of JavaScript to minimize the work as well as the time needed for developing complex or large websites. Those who develop websites also have the option to use different JavaScript frameworks to quicken and effectuate web development.

JQuery is a broadly applied JavaScript library that cuts across many platforms. It is an open source but it is simple to use, speedy and brief. The application programming interface (API) given by jQuery operates seamlessly on the main web browsers. More so, JQuery that is described as feature-sufficient JavaScript library does it lighter for web developers to manage events, shape HTML documents, develop AJAX applications and design animations. At the same time, jQuery may also be used for building a kind of plug-ins by making use of the JavaScript library.

The current web developers thus have the alternative to use jQuery and JavaScript either autonomously or with each other. Nonetheless, it is too significant for people who are interested in web development to know some of the common variations between jQuery and JavaScript. It would be easy for the user to understand about the two by contrasting them in the following four aspects

1) Programming Language and Library

Since JavaScript is a dynamic coding language, it supports structured, imperative, functional and object-oriented programming methods. Again, the dynamic typing and first-class functions cause JavaScript classified as a prototype-based scripting language. jQuery, on the other hand, is a JavaScript library. This structure enables developers to do a number of major web assignments such as event handling, HTML document manipulation, animation, DOM element selection as well as AJAX application building.

2) Scripting Time

In case a programmer chooses to make use of pure JavaScript, he will have no option but to write extra code to fulfill many activities. Furthermore, he has to put additional work and time into debugging and dealing with browser adaptability challenges. For the case of jQuery, programmers are allowed to make use of the available scripting. Thus they can utilize the scripting available in jQuery to perform a number of web tasks without the need to write tiresome lines of code. So, jQuery simplifies the work of web programmers by saving the time and works needed for developing internet applications and modern websites

3) Facilitation of Client-Side Scripting

As you may have known, JavaScript is a client-side scripting language. This makes it simpler for programmers to put into force the user interactivity and give customized systems to users. Nevertheless, programmers have to put down a bit extended lines of code to do a web application in pure JavaScript. That is the reason why web builders usually utilize JavaScript development structures to achieve the scripting roles fast and efficiently. Being a multi-platform JavaScript library, jQuery has traits to realize the basic scripting functionalities. Hence programmers can employ the library to make manageable the client-side scripting of HTML. The widgets, plug-ins and User Interfaces rendered by the framework assistant web programmers to decrease development time to a great extent.

4) Performance

Both run considerably quicker on the newest machines and web browsers. Still, the rate of both jQuery and JavaScript is influenced by the application of former web browsers. Since JavaScript can locate the DOM quicker than jQuery, the developers can readily shorten the costs correlated with the library.j Query makes it comfortable for developers to create great-performing internet application and websites by providing functionality that does not rely on web browsers.

In a nutshell, jQuery is a library of JavaScript language and on the other hand, JavaScript is a powerful and feature-rich coding language. The experienced JavaScript coders can quickly use jQuery to perform various jobs without writing long lines of programs. Nonetheless, they can yet apply jQuery without being skilful in the common client-side scripting language. For that reason, there is the need for programmers to pick jQuery or JavaScript depending on particular requirements of the project.

Even with the above knowledge, there is always a question that most beginners will want to know. That is, whether it is good to learn for the two at a go or learn them one-by-one. Well, that will depend on people and it might not be a big deal. The issue here should be which of the two should one start with.
It is advisable for starters to begin learning JavaScript before jQuery because of the following reasons.

i. If you wish to be an excellent programmer, you have to have the need to know how everything works. Unfortunately, it is not easy to understand how jQuery works without grasping JavaScript.

ii. Quite a number of organizations who are in need of someone who understands jQuery are apparently also looking for someone who comprehends conventional JavaScript.

iii. JQuery is a library, made in Javascript that is the language. The common and practical way has been that it is nearly the fact that knowing about the library without the knowledge of the language is unreasonable if not impracticable, irrespective of the language and the library in question.

Wrapping It Up

Just to wrap up, it is important to put it clear that both jQuery and JavaScript are libraries client-side scripting applied for tasks like validation, constructing visually appealing components such as good navigation menus and so on. Because the goal of the two technologies (JavaScript and jQuery) is similar, the decision of adopting a certain technology rests with the programmer. It seems like presently, jQuery is fast gaining prevalence over JavaScript
