JSjet was introduced in version 2016 CI 3 of Webclipse and MyEclipse.
Syntax Highlighting for JavaScript
JSjet utilizes the Acorn parser to provide unique colors for a multitude of JavaScript elements based on semantics. Syntax highlighting includes support for new ES 6 constructs like classes, templates, import/export statements and many more.

Setting Preferences for Syntax Highlighting
You can modify many of the color and styling preferences for elements affected by syntax highlighting. To edit the default settings for an element, go to Windows>Preferences>(MyEclipse>)JavaScript>Editor>Syntax Coloring. Some elements are always styled and cannot be disabled, the Enable checkbox is grayed out. For others, you can decide whether you want to enable or disable syntax highlighting. For each element you can select the desired color and styling.
