Outline View
The Outline view depicts a structured view of the functions and variables of a JavaScript editor, giving you a quick understanding of how the code is structured. Click an element in the outline to jump to that section in your code.
If the view is not visible in the current perspective, select Window>Show View>Other>General>Outline from the toolbar.

Open Declaration
A reliable Open Declaration option is a real timesaver for the modern developer, especially when working with a large number of libraries and you really don’t recall where a given function is coming from. Jump to the declaration for the current object, whether a method, field, or function, including declarations in the current file or another file in the project.
Jump to declarations using any of the following methods:
- Press the Ctrl key and click an element.
- Select an element and press F3.
- Right-click from the element and select Open Declaration from the context menu.

- Select Navigate>Open Call Hierarchy from the menu bar.
- Select an element and press Ctrl+Alt+H.

Open the Type Hierarchy view using any of the following methods:
- Right-click an element and select Open Type Hierarchy from the context menu.
- Select Navigate>Open Type Hierarchy from the menu bar.
- Select an element and press F4.

Search
Use the JavaScript Search feature when you need to do advanced code analysis. Not only does it support searching for different types of constructs, our advanced JavaScript knowledge correctly identifies different types of references. No longer will you get a variable read if you are searching only for writes, or function references if you’re only looking for the declaration. The search also works well with OOP and understands ES6 syntax. You can search within OOP and ES6 classes too, and, at a more fundamental level, it understands the difference between methods and functions, or fields and variables. In the following example, the search results display only the write access to chromeWindow while ignoring two other references to that variable because we limited the search to Write accesses.
