Pycharm Community Javascript



PyCharm is also available as a snap package. If you’re on Ubuntu 16.04 or later, you can install PyCharm from the command line. Sudo snap install pycharm-professional pycharm-community -classic.

  • PyCharm also includes JavaScript support of various libraries through a toolbox called JS Toolbox. The following screenshot shows this. It also includes various attributes which are necessary for the JavaScript file configuration. The list of attributes and configurations is shown below −.
  • PyCharm costs around $200 a year. There is a community version of PyCharm which is free to use commercially but it lacks many features (like remote debugging support, advanced Django support and support for JavaScript and CSS) that make PyCharm attractive. On the other hand, VS Code is FOSS (Free and Open-Source Software). This is a no-brainer.

In this chapter, we will focus on main features in using JavaScript in PyCharm editor. When a user implements JavaScript library through URL, PyCharm intends to download a local copy so it can be used for completion and code analysis.

Consider the sample code of our HTML file as shown below, which we created in the previous chapter −

For each HTML file or JavaScript file, you can check the external libraries loaded through Settings configuration of PyCharm Editor. Observe the screenshot shown below for a better understanding −

Note that you cannot see any library unless you download and implement it. PyCharm also includes JavaScript support of various libraries through a toolbox called JS Toolbox. The following screenshot shows this.

It also includes various attributes which are necessary for the JavaScript file configuration. The list of attributes and configurations is shown below −

Observe that it includes various parameters such as Unit test suffix, File suffix, View suffix, Search URL and the specific Root directory.
