const _ = require('@nrpope/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
function1(head)
: requires an array as an argument and returns the first item in an arrayfunction2(tail)
: requires an array as an argument and returns all but the first item of the arrayfunction3(middle)
: requires an array as an argument --if array has odd length, it will return the middle item in an array --if array has even length, it will return the two middle items in an arrayfunction4(assertArraysEqual)
: asserts that the actual and expected arrays are both equalfunction5(eqArrays)
: equires an array as an argument and returns if they are of equal valuefunction6(head)
: requires an array as an argument and returns the last item in an arrayfunction7(assertEqual)
: asserts that both the expected and the actual values are equalfunction8(flatten)
: Given an array with other arrays inside, it can flatten it into a single-level array.function9(countOnly)
: This function takes in a collection of items and return counts for a specific subset of those items.function10(letterPositions)
: Will return all the indices (zero-based positions) in the string where each character is found.function11(findKeyByValue)
: Takes in an object and a value. It scans the object and returns the first key which contains the given value. If no key with that given value is found, then it returns undefined.function12(eqObjects)
: Will take in two objects and returns true or false, based on a perfect match.function13(without)
: This function takes in a source array and a itemsToRemove array. It returns a new array with only those elements from source that are not present in the itemsToRemove array.
