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 @lun_ji/lotide
Require it:
const _ = require('@username/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
tail (array)
: return an array without the first item.eqArrays(array1, array2)
: compare two array, return 'they are the same' if they are the same.assertArraysEqual(array1, array2)
: compare two arraries, return true if they are the same.middle(array)
: return the middle items for an array, return middle one if it contain odd number of items, return middle two if it contain even number of items.assertEqual(array1, array2)
:head(array)
: return the first item of an array.assertObjectsEqual(object1, object2)
: compare two objects and return "they are the same" if all the keys and items in the two objects are the same.countLetters(string)
: count the number of each letter in a string, an object will be returned.countOnly(string, 'X')
: count the frequency of the letter 'X' in the string.findKey(object, 'key')
: find the value of the input key in the given object.findKeyByValue(object value)
: find the first key of the given value in the object.letterPositions(string, 'X')
: return the first index of letter 'X' in the given string.
