extended version of lodash, with the following functionality (see tests for more examples)

npm i --save @symbolic/lodash

import _ from '@symbolic/lodash'

contributing

1. create a new folder for the new function
2. implement it following an existing pattern (including existing variable naming patterns)
3. test it to 100% coverage with clean descriptions
4. add it to index.js as an export in alpabetized order
5. document it in README.md in alpabetized order with an explanation and example

functions

arrayMove

• accepts an array, old index, and new index to move an item within an array
• useful for drag+drop reordering

_.arrayMove([1, 3, 2], 2, 1) -> [1, 2, 3]

• accepts a date as an argument and returns a label in a format according to the difference between the date and current time

_.labelForMoment(<today at 10 am>) -> '10:00 am'
_.labelForMoment(<yesterday at 10 am>) -> 'm/d 10:00 am'
_.labelForMoment(<lastYear at 10 pm>) -> 'm/d/yy 22:00 pm'
