Track Comments

Comments beginning with // track:. See comment_prefixes.md

Track Comment Registry

• track: type check: A condition that's used to check the type of an imput.
• track: adapt A value can by adapted from another type at this line.
• track: bounds check: A condition that's used to check the bounds of an array or other list-like entity.
• track: ruleset A series of conditions that early-return or continue
• track: object description in comment A comment above the creation of some object which could potentially have a description property. This is especially relevant if the object is stored in some kind of registry where multiple objects could be listed in the console.
• track: slice a prefix A common pattern where a prefix string is "sliced off" of another string to obtain a significant value, such as an indentifier.
• track: actor type The sub-type of an Actor object is checked.
• track: scoping iife An immediately-invoked function expression specifically used to reduce scope clutter.
• track: good candidate for sequence Some code involves a series of similar steps, or there's a common behavior that should happen in between. The Sequence class is good for this so it might be a worthy migration.
• track: opposite condition of sibling A sibling class, function, method, or other construct of source code has a boolean expression which always evaluates to the opposite of the one below this track comment.
• track: null check before processing An object could be undefined or null, additional processing occurs after a null check, and the unprocessed object is not relevant to the rest of the code. If the code for obtaining the object and processing it is moved to a function outside, then the null check should result in a early return of null; this code with the track comment may have additional logic for the null/undefined case.
• track: manual safe object This code manually creates a new "client-safe" version of some object that's in scope. This could be either to pass onto the browser or to pass to something like the notification service.
• track: common operations on multiple items A patterm which emerges when multiple variables have common operations done upon them in sequence. It may be applicable to write an iterator in the future, or something will come up that require these to be handled with a modular approach instead.
