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 @v_lane/lotide
Require it:
const _ = require('@v_lane/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
assertArraysEqual(arr1, arr2): given two arrays, logs to console a message confirming if arrays are equal or not equal.assertEqual(actual, expected): given two values, logs to console a message confirming if values are equal or not equal.assertObjectsEqual(object1, object2): given two objects, logs to console a message confirming if objects are equal or not equal.countLetters(sentence): given a sentence as a string, returns object containing count (values) of each of the letters (keys) in sentence.countOnly(allItems, itemsToCount): given array of items and object(value: item, key: true/false), returns object of ONLY the count of items in array that were marked true in object. Returned object(value: item, key: count of item in array).eqArrays(arr1, arr2): given two arrays, returns true if arrays are equal or false if arrays are not equal.eqObjects(object1, object2): given two objects, return true if objects are equal or false if objects are not equal.findKey(object, callback): given object and callback, scans object for first key for which the callback returns truthy value and returns this key. If no key found, returns undefined.findKeyByValue(object, value): given object and value, scans object and returns first key which contains given value. If no key found with value, returns undefined.flatten(array): given array containing elements including nested arrays, returns 'flattened' array with only 1 nested array level.head(array): given array, returns first value of array.letterPositions(sentence): given sentence as a string, returns an object that shows all indices (values) where each letter (key) is found.map(array, callback): given array and callback, returns new array based on results of callback function.middle(array): given an array, return middle-most element(s) as array. Odd-length array will return array with 1 value, even-length array will return array with 2 values.tail(array): given array, return as array all values EXCEPT first value.takeUntil(array, callback): given array and callback, return slice of the array with elements taken from the beginning until callback returns truthy value.without(source, itemsToRemove): source array and 'items to remove' array, return new array with only elements from 'source' array that are NOT present in 'items to remove' array.
