Use cases

Let's have a list of real world use cases:

• jQuery's $.extend and Underscore/Lodash _.extend and _.defaults iterate over own and inherited enumerable properties. In the case of Lodash, keysIn is used to get the property names to iterate over. It's also used in Underscore _.functions and Lodash's _.functionsIn.

• The use of valuesIn can be mapped to the use of values which is used in lib helpers like Underscore/Lodash includes for seeing if a value is in an object or sample which grabs a random value from an object.

• I've found folks dig the inherited forms of these methods when working with data objects returned by Node.js DB packages (<TODO get names of packages>).

  mongoose

• I have a method _.toPlainObject which flattens inherited properties to own properties of a new object. This is handy for working with Object.assign and keysIn is used to implement that.

No target file is named. Start by locating the repository's documentation or examples area, then compare the listed jQuery, Underscore/Lodash, Mongoose, and Object.assign use cases with existing material. Done means adding a concise, accurate list and replacing the TODO package name if verified.
