npm install @justinbennett/lotide

Require it:

const _ = require('@justinbennett/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• assertEqual(): Assertion function to strictly assess primitive data types.
• assertArraysEqual(): Assertion function utilizing eqArrays to test equality of objects.
• assertObjectsEqual(): Assertion function utilizing eqObjects to test equality of objects.
• countLetters(str): Function that counts the amount of alpha-numeric characters within a given string.
• countOnly(): From an array of items (arg 1), return a count of only the given values in (arg 2).
• eqArrays(): Function to strictly and deeply verify equality of arrays.
• eqObjects(): Function to strictly and deeply verify equality of objects.
• findKey(): Find the first key value matching the results of a callback function.
• findKeyByValue(): Given the value, finds the matching key of an object.
• flatten(): Flattens nested array values by one level.
• head(): Returns the first value in an array.
• letterPositions(): Given a string, returns an object of the unique characters and all indicies that character is found.
• map(): A custom variation of .map() that alters values in an array based on the given callback.
• middle(): Returns the middle value(s) in an array.
• tail(): Returns all but the first value in an array.
• takeUntil(): Returns all values in a given array up until the given callback.
• without(): Returns a copy of an array (arg 1) with values given in arg 2 removed.
