A mini clone of the Lodash library.
BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.
This project was created and published by me as part of my learnings at Lighthouse Labs.
Install it:
npm install @ramosd/lotide
Require it:
const _ = require('@ramosd/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
head(array): Returns the first element of the array.tail(array): Returns a new array without the first element.middle(array): Returns the middle element(s) of an array. For even-length arrays, it returns the two middle elements.assertEqual(actual, expected): Compares two primitive values and prints a message indicating whether they are equal.assertArraysEqual(actual, expected): Compares two arrays and prints a message indicating whether they are equal.assertObjectsEqual(actual, expected): Compares two objects and prints a message indicating whether they are equal.countLetters(string): Returns an object with the count of each letter in a string.countOnly(allItems, itemsToCount): Counts how many times specified items appear in an array.eqArrays(arr1, arr2): Compares two arrays for equality.findKey(object, callback): Finds the first key in an object that satisfies the given callback function.findKeyByValue(object, value): Finds the first key in an object that contains the specified value.flatten(array): Flattens a nested array into a single array.letterPositions(string): Returns an object with the positions (indices) of each character in the string.map(array, callback): Creates a new array based on applying the callback function to each element in the original array.takeUntil(array, callback): Returns a slice of the array starting from the beginning until the callback function returns a truthy value.without(array, itemsToRemove): Returns a new array excluding any elements that are in theitemsToRemovearray.
