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

Call it:

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

• assertEqual(actual, expected): comparing the actual and expected values, print out message to show if they are same or not
• assertArraysEqal(arr1, arr2): comparing arr1 and arr2, print out message to show if they are same or not
• assertObjectsEqual(object1, object2): comparing object1 and object2, print out message to show if they are same or not
• eqArrays(actual, expected): returns true if arr1 has same elements as arr2, otherwise, return false
• eqObjects(actual, expected): returns true if object1 has same properties as object2, otherwise, return false
• countLetters(string): return an object with the occurance of each letter
• countOnly(allItems, itemsToCount): returns an object that count the items from allItems if it exists in itemsToCount with a true value
• findKey(object, callback): return the key that has a value satisfying the call back function
• findKeyByValue(object, value): return the key by value
• head(array): returns the head of array
• middle(array): returns middle of array
• tail(array): returns tail ofr array
• flatten(array): returns the flattened the array
• map(array, callback): returns an array that satisfies the callback function
• letterPositions(string): returns an array of the position(s) of input letter(s)
• takeUntil(array, callback): returns an array that contains all elements before the callback function is satisfied
• without(source, itemToRemove): returns an array of source without the elements itemToRemove
