This project was created and published by me as part of my learnings at Lighthouse Labs.

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

Call it:

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


The following functions are currently implemented:

  • head(array): returns the first element of an input from array
  • tail(array): return every item from the input array except for the first item
  • middle(array): returns the middle index from the input array, if there are an even number of items in the array, it will return the middle two items
  • assertArraysEqual(array1, array2): determines if arrays are equal
  • assertEqual(actual, expected): determines if strings are equal
  • assertObjectsEqual(obj1, obj2): determines if objects are equal
  • countLetters(array): determines letter count of an object
  • eqArrays(array1, array2): determines if arrays are equal, returns boolean
  • eqObjects(obj1, obj2): determines if objects are equal, returns boolean
  • findKey(obj, callback): returns object key that matches the callback functions key finding function
  • findKeyByValue(obj, value): returns key given a value
  • flatten(array): returns a flattened 1-dimensional array
  • letterPositions(array): takes in a sentence and returns an object with the indexes of every letter in the sentence
  • map(array, callback): takes in an array, goes through every index of the array with the callback function, and returns a new array with the items filtered by the callback
  • takeUntil(array, callback): takes in an array and return new array filtered by the callback
  • without(source, itemsToRemove): takes in source and output the array without the items indicated on the itemsToRemove.
