JavaScript (JS) is a front-end web development language and Pace Wisdom is a recognised JavaScript development company. Our developers use JS for all things interactive on a website or web application. In the days before the prevalence of JS, websites were built with static HTML elements with flat formatting with a few interactive elements. However, JavaScript changed that as it was the first client-side, an OOP scripting language. Pace Wisdom developers employ JS to develop interactive websites and web applications for your enterprise ensuring a high level of interactivity and a memorable user experience.
There is a considerable influence of JavaScript on modern front-end technology, and it includes a large array of technologies with JavaScript at the core which have helped to streamline, support, and strengthen already existent JavaScript capabilities.
Pace Wisdom has recognized that there are multiple server-side JavaScript programming environments such as Node.js along with technologies such as React, Express.JS, and Koa.js. Front-end JS frameworks include Ember.js and AngularJS and JSON, a JS object notation language. JS libraries include jQuery, compilers and AJAX.
JavaScript: Method Behind the Precision
Two major elements of JavaScript
Functions:
Blocks of JS code that run on command and ‘statements’, which are instructions that are executed by the browser. All of the ‘code’ in JS is a string of statements that are executed in order.
Objects:
Core principal of JavaScript. All elements in the JS environment are objects, and all objects have variables or ‘properties’ and ‘methods’.
JavaScript Engines
Pace Wisdom utilizes JavaScript to build and deploy enterprise oriented web solutions as JavaScript is a high-level programming language indicating that it is a readable, flexible, and easier to implement than a coding language like ‘C’.
However, JavaScript needs to be compiled to native machine code in order to enable computer systems to be able to read and execute the code. This is where the significance of the JavaScript engine becomes evident and the definition of the engine as a ‘process virtual machine assisting hardware in interpreting, compiling, and executing JavaScript code.
JavaScript V8: Google Chrome, Opera
Node.js
SpiderMonkey: Mozilla Firefox
JavaScriptCore: Safari
Chakra: IE, Edge
Developers at Pace Wisdom have understand that a JavaScript engine provides JS with essential components needed to run on a browser, such as an interpreter, a compiler, and a runtime environment.
JavaScript Frameworks
While developing cutting edge JS applications for your enterprise, Pace Wisdom takes the help of JavaScript frameworks. These frameworks consolidates complicated commands into well structured chunks of JavaScript code to ensure quick and easy solution developement for our developers.
jQuery An extremely popular and highly preferred JavaScript library among developers, with a ‘code less, function more’ framework philosophy that helps jQuery maintain uniform performance across multiple browsers.
AngularJS A robust, oriented towards desktop apps and apt for data-heavy sites, the AngularJS framework provides a much needed module-based structure for building complicated applications easily
Backbone.js Lightweight JS framework that’s a ‘pared-down’ alternative to full-featured frameworks.
Bootstrap: A mobile-first framework using HTML, CSS and JavaScript to facilitate rapid responsive app development.
Ember.js Lightweight JS framework Ember has been used by sites to increase site performance. Ember is equipped with a built-in data module and template engine.
Meteor JS Open-source, real-time framework, built on top of Node.js and works closely with MongoDB.
Node.js Server-side development environment designed to use JavaScript to build back-end applications with its own components such as frameworks, task-runners and plugins.
Express.js Server-side JavaScript framework running on the Node.js platform.
Koa.js Next-generation framework for Node.js following in the footsteps of Express.js.
Prototype Framework with a built-in API making common JS tasks streamlined to code.
MooTools A JS framework with an API which streamlines common tasks and which includes effects and animation.
ReactJS Facebook’s JavaScript library excellent for building the user interface of web applications.
React Native A mobile library used to build a natively rendered user interface for mobile applications.
JavaScript Development Tools
One of major strengths of JavaScript as Pace Wisdom developers have pointed out is that this language does not require expensive development tools. Our developers can initiate a project with a text editor such as Notepad. Additionally, since JS is an interpreted language inside the context of a web browser, a compiler is not a necessity during the development phase.
Microsoft FrontPage
Microsoft released a popular HTML editor called FrontPage that provides web developers at Pace Wisdom with a number of JavaScript tools to assist in the creation of interactive websites.
Macromedia Dreamweaver MX
Macromedia Dreamweaver MX, is popular for being a HTML and JavaScript editor in the professional web development world, that provides prebuilt JavaScript components. Dreamweaver also integrates well with databases and conforms to new standards such as XHTML and XML.
Macromedia HomeSite 5
Macromedia released HomeSite 5, an HTML and JS based editor that helps in the effective management of personal websites.
Why does Pace Wisdom Recommend JavaScript?
One of major strengths of JavaScript as Pace Wisdom developers have pointed out is that this language does not require expensive development tools. Our developers can initiate a project with a text editor such as Notepad. Additionally, since JS is an interpreted language inside the context of a web browser, a compiler is not a necessity during the development phase.
Browser Support
To use JavaScript plugins are not a requirement. This is because all browsers have accepted JavaScript as a scripting language and provide integrated support for the JS code. All Developers need to handle a few of the tasks dependent on DOM (Document Object Model) of different browsers.
Client Side & Server Side
As JavaScript has access to the Document Object Model of various browsers, developers at Pace Wisdom can change the structure of web pages at runtime. Owing to this, JavaScript can be used to add different effects to webpages. Also, JavaScript is implemented on the server side and as an example, in ‘Alfresco’ which is an open source enterprise content management system, JavaScript is used in creating webscripts. This makes adding custom tasks to Alfresco simpler for our developers.
Functional Programming Language
In JavaScript, function could be assigned to variables just like any other data types. Clearly, this gives developers the ability to code in a ‘functional programming style’.
Support for Objects
JavaScript is an object oriented language. However, the way JavaScript as a language handles objects and inheritance differs from related object oriented programming languages like Java. Hence, JavaScript supports most of the object oriented concepts while being simple to learn and implement.
These are a few features that give JavaScript the ability to handle simple user interface based as well as complex server side tasks. Due to these characteristics JavaScript has remained as a popular programming language quite some time now. It is also the preferred coding language for developers who are inclined toward knowing computer programming as JavaScript supports object oriented as well as function concepts.
Advantages of JavaScript
Speed
JavaScript is quick as it is a client-side code with functions that can be executed promptly without the delay associated with communicating with servers.
Simplicity
JavaScript is relatively simple to learn and implement.
Versatility
JavaScript gels well with other coding languages and can be used in multiple applications. JavaScript can also be used inside scripts written in other languages such as Perl and PHP.
Server Load
Being client-side JavaScript reduces the demand on the website server.
