Install it:
npm install @bushra.patel/lotide
Require it:
const _ = require('@bushra.patel/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
head(arr)
: Returns the first item in the array.tail(arr))
: Returns the "tail" of an array: everything except for the first item (head) of the provided array.middle(arr)
: Returns the middle-most element(s) of the given array.flatten(arr)
: Returns a "flattened" version of the array (including nested arrays).without(source, itemsToRemove)
: Returns a subset of a given array, removing unwanted elements.takeUntil(array, callback)
: Keeps collecting items from a provided array until the callback provided returns a truthy value.map(array, callback)
: Returns a new array based on the results of the callback function.countOnly(allItems, itemsToCount)
: Returns an object containing counts of everything that the input object listed.countLetters(sentence)
: Returns a count of each of the letters in that sentence.letterPositions(sentence)
: Returns all the indices (zero-based positions) in the string where each character is found.findKeyByValue(objectToScan, value)
: Returns the first key which contains the given value. If no key with that given value is found, then it should return undefined.findKey(objectToScan, callback)
: Returns the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.assertEqual(actual, expected)
: Compares the two values it takes in and print out a message telling us if they match or not.eqArrays(array1, array2)
: Returns true or false, based on a perfect match.assertArraysEqual(array1, array2)
: Prints (console.log) an appropriate message to the console.eqObjects(object1, object2)
: Returns true or false, based on a perfect match.assertObjectsEqual(actual, expected)
: Prints (console.log) an appropriate message to the console.
