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 @mogar/lotide
Require it:
const _ = require('@mogar/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
assertEqual(actual,expected): Compares if two values match and returns a string stating if the assertion passed or failed.assertArraysEqual(array1,array2): Compares if two arrays match and returns a string stating if they are equal or not.assertObjectEqual(actual,expected): Compares if two objects match and returns a string stating if the assertion passed or failed.eqArrays(array1,array2): Compares if two arrays match returns true if they do and false if they dont. Able to handle nest arrays.eqObjects(obj1,obj2): Compares if two objects match returns true if they do and false if they dont. Able to handle nest objects.countLetters(str): Takes a string and returns an object with the letters as keys and value being the number of times they had occured.countOnly(allItems,itemsToCount): Takes an array and object, returning a new object. The object contains all the array values that match the object and the value being the number of times they had occured.findKey(obj,callback): Takes an object and callback function, returning the first object key that returns true from callback.findKeyByValue(obj,value): Takes an object and value, returning the first object key that matches the given value.flatten(array): Takes an array with nested values and returns a new single nested array with nested values.head(array): Takes an array and returns the first value in the array.letterPositions(sentence): Takes a string and returns an object with the keys of the letters, and a array of all the indexes where they occured.map(array,callback): Takes an array and callback function, returning a new array with the return value of each element being passed through callback.middle(array): Takes an array and returns the value of the middle index. If array is even, it will return the two values adjacent to the middle.tail(array): Takes an array and returns a new array with all the values except the first element.takeUntil(array,callback): Takes an array and callback function, returning a new array of all the values that appeared prior to value that returns true when passed in call back.without(source,itemsToRemove ): Takes a source array and a array of itemstToRemove, returning a new array of all the values in source array that were not in itemsToRemove array.
