Software, devices and technical concepts, explained clearly.

DOM presents the document as linked nodes that the program can read and modify. The difference between text and HTML is important when updating content.
The name ending in .pdf does not prove the file format.
Enum groups symbolic names with their values. For example, Status = Enum('Status', {'DRAFT': 'draft', 'LIVE': 'live'}) lets code use Status.DRAFT instead of arbitrary free text.
The listener associates an event with a function. A separate solution is whether to cancel the standard browser action.
every() checks that all elements meet a condition. In an empty array, there is no element to break it.
contextlib.ExitStack collects context managers and cleanup actions. It helps when input determines how many files need opening rather than the number being fixed in advance.

The group gets its own title, instead of the relationship between the fields being passed only with a layout.
figure can merge a standalone illustration, chart, or other material with an explanation.
Filling an array does not create an independent copy for each position.
filter() preserves the elements that fulfill a condition. The result may be shorter than the entrance or it may be empty.
