  • _, lodash, dash - Lodash is exposed.
• Checks
  • isArray, isList will be true in array filter order

  • isAllString - returns true if all the items in a list are string
  • isAllList - returns true if all the items in a list are list
  • isAllObject, isCollection - returns true if all the items in a list are objects
• examples:

  // filter Truthy values
  [ "", "Hi", 1, 0, false, true, [], {}, null ]
  // filter code = Boolean(a)
  // filter to  [ "Hi", 1, true, [], {} ]
  
  // filter only string
  [ "", "Hi", 1, 0, false, true, [], {}, null ]

  // filter by value length
  { "name": "foo", "id": 1, "label": "first item" }
