Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

assertArraysEqual(...): assertion check for eqArrays assertObjectsEqual(...): assertion check for eqObjects assertEqual(...): uses strict comparison on two values countLetters(...): take in a string and then return a count of each of the letters in that string countOnly(...): takes in a collection of items and return counts for a specific subset of those items eqArrays(...): calls eqArrays and returns a message to console if arrays are the same eqObjects(...): function that can compare two arrays for a perfect match. findKey(...): checks if key exists in object findKeyByValue(...): which takes in an object and a value. It will scan the object and return the first key which contains the given value. If no key with that given value is found, then it will return undefined. head(...): returns the first element of an array letterPositions(...): return all the indices (zero-based positions) in the string where each character is found. map(...): The map function will return a new array based on the results of the callback function. middle(...): Returns the middle value of an array. If array is even, returns the middle two. tail(...): Returns an array with the first element removed takeUntil(...): The function will return a "slice of the array with elements taken from the beginning." It will keep going until the callback/predicate returns a truthy value. without(...): Removes unwanted items from an array
