applyArrayIndices([1, 2], 'array.$.subArr.
get
(
  target: any,
  path: string | number,
  options?: {
    default?: any,
  }
): any
Get a value from a target object, using path with dot-notation. Returns undefined or the optional default value if the value is not found.
get({ a: [{ b: 1 }] }, 'a.0.b'); // returns 1
get({ a: [{ b: 1 }] }, 'a.7.b', { default: 4 }); // returns 4
mergeObjects
(objects: objects[]): object
Merges an array of objects using lodash.merge
mergeObjects([
  { a: 1, c: 4 },
  { a: 2, b: 3 },
]); // returns { a: 2, b: 3, c: 4 }
omit
(object: object, list: string[]): object
Remove an array of keys from a object. Uses unset from this package.
omit({ a: 1, b: 2, c: 3, d: 4 }, ['a', 'd']); // returns { b: 2, c: 3 }
serializer
serializer.copy
serializer.deserialize
serializer.deserializeFromString
serializer.serialize
serializer.serializeToString
set
(
  target: any,
  path: string,
  value: any
): void
Sets a value in a object at a key given by path.
const obj = { a: 1 };
set(obj, 'b.c', 2);
// obj becomes { a: 1, b: { c: 2 } }
stableStringify
(
  object: any
  options?: {
    cmp?: function,
    cycles?: boolean,
    space?: string | number,
    replacer?: function
  }
)
Derived from https://github.com/substack/json-stable-stringify
Returns a deterministic JSON stringified object.
swap
(
  arr: any[],
  from: number,
  to: number
)
Swaps the object at the from index with the object at the to index.
swap([0, 1, 2, 3, 4], 2, 3); // returns [0, 1, 3, 2, 4]
type
unset
(object: object, property: 'string')
Unset a property on a object. Supports dot-notation.
const obj = { a: { b: [] } };
unset(obj, 'a.b'); //
// obj becomes { a: {} }
urlQuery
urlQuery.parse
(string: string): object
Parse a urlQuery serialized by urlQuery.stringify.
urlQuery.parse('a=%7B%22b%22%3A%221%22%7D'); // returns { a: { b: '1' } }
urlQuery.stringify
(object: object): string
Serialize a urlQuery object to use as URL query parameters. Nested objects are serialized using serializer.serializeToString.
urlQuery.stringify({ a: { b: '1' } }); // returns 'a=%7B%22b%22%3A%221%22%7D'
