filterPropType(data, prop, allowedType)

Filters all objects in data by checking if the value of a given property prop in each element is of the correct data type. allowedType works with any string from the following list (case-insensitive):

"Boolean", "Integer", "Number", "String", "Array", "Object"

Returns an array with only those objects who have all required properties with the correct data type. This function is useful to get rid of "dead" data elements that cannot be displayed or used properly.

Example:

If you have data like this:

let superheroes = [
  {Name: "Steppenwolf", Weight: "91"},
  {Name: "Storm", Weight: "57,8"},
  {Name: "Sunspot", Weight: 77},
  {Name: "Superboy", Weight: 68.3},
  {Name: "Superboy-Prime", Weight: [77, 99]},
  {Name: "Supergirl", Weight: "unknown"},
]

This finds and returns all elements in superheroes whose Weight has the data type number:

let filteredHeroes = gmynd.filterPropType(superheroes, "Weight", "Number");

This is the result:

[
  {Name: "Sunspot", Weight: 77},
  {Name: "Superboy", Weight: 68.3},
]

Note: 77 is an Integer and all Integers are Numbers.
