Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
assertArraysEqual(arr1, arr2)
: takes two arrays as arguments and asserts if they are equal or notassertEqual(val1, val2)
: takes two data types as arguments and asserts if they are strictly equal or notassertObjectsEqual(obj1, obj2)
: takes two objects as arguments and asserts if they are equal or notcountLetters(str)
: takes a string as an argument and returns an object containing each letter in the string and the number of times that letter appears in the stringcountOnly(arr, obj)
: takes an array and an object as arguments and returns an object containing counts of everything that the input object listedeqArrays(arr1, arr2)
: takes two arrays as arguments and determines if they are equal or noteqObjects(obj1, obj2)
: takes two objects as arguments and determines if they are equal or notfindKey(obj, cb)
: takes an object and a callback function as arguments and returns the key of the object that the callback function specifies needs to be foundfindKeyByValue(obj, val)
: takes an object and value as arguments and returns the first key of which the given value is found to be a value offlatten(arr)
: takes an array that may or may not contain more arrays as an argument and turns it into an array of values only with no arrays inside the overarching arrayhead(arr)
: takes an array as an argument and returns the first element in that arrayletterPositions(str)
: takes a string of characters as arguments, removes the spaces, and returns an object containing the letters as keys and their index positions as arrays of valuesmap(arr, cb)
: takes an array and a callback function as arguments and returns an array containing the elements of the original array with the callback function applied to each elementmiddle(arr)
: takes an array as an argument and returns the middle element. If the array has an even length, returns the middle two elementstail(arr)
: takes an array and returns the array without its first elementtakeUntil(arr, cb)
: takes an array and a callback function as arguments and returns a sliced version of the array that stops depending on the specified callbackwithout(arr1, arr2)
: takes a source array and an item removal array as arguments and returns the source array without any of the items from the item removal array
