What Is a Front-End Developer?
The objective of designing a site is to ensure that when the users open up the site they see the information in a format that is easy to read and relevant. This is further complicated by the fact that users now use a large variety of devices with varying screen sizes and resolutions thus forcing the designer to take into consideration these aspects when designing the site. They need to ensure that their site comes up correctly in different browsers (cross-browser), different operating systems (cross-platform) and different devices (cross-device), which requires careful planning on the side of the developer.
Typically, a person enters into the field of front-end development by learning to develop HTML, CSS, and JS code, which runs in a web browser, headless browser, WebView, or as compilation input for a native runtime environment. These four run times scenarios are explained below.
A web browser is software used to retrieve, present, and traverse information on the WWW. Typically, browsers run on a desktop or laptop computer, tablet, or phone, but as of late a browser can be found on just about anything (i.e, on a fridge, in cars, etc.).
The most common web browsers are (shown in order of most used first):
Headless browsers are a web browser without a graphical user interface that can be controlled from a command line interface programmatically for the purpose of web page automation (e.g., functional testing, scraping, unit testing, etc.). Think of headless browsers as a browser that you can run from the command line that can retrieve and traverse web pages.
The most common headless browsers are:
Webviews are used by a native OS, in a native application, to run web pages. Think of a webview like an iframe or a single tab from a web browser that is embedded in a native application running on a device (e.g., iOS, android, windows).
The most common solutions for webview development are:
- Cordova (typically for native phone/tablet apps)
- NW.js (typically used for desktop apps)
- Electron (typically used for desktop apps)
