I am wanting to store TaskPaper-like tasks in a JavaScript object. Suppose I have a task like
- Post to StackOverflow @priority(2) @due(2016-05-03) @flagged
This would turn into
{"name":"Post to StackOverflow", "priority": 2, "due":"2016-05-03", "flagged":"value"}
Flagged doesn't need a value and all I can think of is to use true or null
I would like to later filter tasks using if key in object and having true/false values wouldn't work with my workflow.
What would the SO community recommend as best practices.

Object Keys in JavaScriptEach key in your JavaScript object must be a string, symbol, or number.
The short answer is "no". All JavaScript object keys are strings. Even if you pass an object as a key, the object's toString() will be called on it, and the key will be stringified to [object Object] .
Restrictions in Naming Properties JavaScript object key names must adhere to some restrictions to be valid. Key names must either be strings or valid identifier or variable names (i.e. special characters such as - are not allowed in key names that are not strings).
If you do something like if (myobj.flagged), then if your value of flagged is true, the test passes. If the flagged property doesn't exist, then you get undefined which is falsy. So it works with flagged:true, flagged:false and even no flagged property. So use true, and omit the property altogether when it's not supposed to be there (so for...in would work in that case).
