@techvisum/lotide v1.0.0

Lotide

A mini clone of the Lodash library.

Purpose

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.

Usage

Install it:

npm install @techvisum/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(arr): return first array element
• tail(arr): return all array elements except first
• middle(arr): return middle element of an array
• assertEqual(actual, expected): assert whether two inputs are same or not
• assertArraysEqual(array1, array2): assert whether two arrays are same or not
• eqArrays(array1, array2): check whether two arrays are same or not
• assertObjectsEqual(object1, object2): assert whether two objects are same or not
• countLetters(input): return a count of each of the letters in input string.
• countOnly(arr, obj): return an object containing counts of everything that the input object listed.
• eqObjects(obj1, obj2): check whether two objects are same or not
• findKey(obj, callback): It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• findKeyByValue(obj, value): scans the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• flatten(arr): It will take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• ` letterPositions,
• map(arr, callback): return a new array based on the results of the callback function.
• takeUntil(array, callback): The function will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• without(sourceArr, itemsToRemove): return a new array with only those elements from sourceArr that are not present in the itemsToRemove array.
