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.

Install it:

npm install @htkim94/lotide

const _ = require('@htkim94/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns first element of input array.
• tail(array): remove first element of input array and returns rest in new array.
• middle(array): returns middle-most index element of input array in new array. Returns two if input array length is even number.
• countLetters(string): returns an object with key of characters and value of occurence in the input string.
• countOnly(array, object): function will take an array (list of items) and find/count for the key with true value from input object and returns new object of found/counted items.
• eqArrays(array1, array2): function will compare two input arrays (works with nested as well), and return true if they have same values at every index.
• eqObjeccts(obj1, obj2): function will compare two input objects (works for nested objects and value of array) and return true if both objects have same keys and values.
• findKey(obj, callback): returns the key of input object which matches the result of callback function.
• findKeyByValues(obj, value): returns the key of input object with the input value.
• flatten(arr): takes nested array and returns flat (single nest) array.
• letterPositions(string): takes an input of string and returns as object with key of character and value of positions (array).
• map(array, callback): mini copy of existing JS method map function.
• takeUntil(array, callback): loops through input array and push only the elements which is true to the callback function. Returns array of pushed elements.
• without(array, value): returns new array with same values of input array only without the input value element.
