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 @jaxson_baerg/lotide
Require it:
const _ = require('@jaxson_baerg/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]

The following functions are currently implemented:
-
head(array)
: returns the first element of an array -
tail(array)
: returns everything after the first element of an array -
middle(array)
: returns the middle on an array -
without(array, toRemoveFromArray)
: returns an array with all elements specified in second parameter removed -
map(array, function)
: returns an array with each element containing the result of the function parameter on initial element -
takeUntil(array, funciton)
: returns an array containing all elements until element meets function parameter requirements -
flatten(array)
: returns array flattened, all nesting removed -
letterPositions(string)
: returns object with each key being a letter and each key's value being the indexes of which it appears in the string parameter -
countLetters(string)
: returns an object with each key being a letter and each key's value being the number of times it appears within the string parameter -
countOnly(array, object)
: returns an object with each key being the element in the array parameter that matched with a key in the object parameter and each value being the number of times it was counted within the array parameter -
findKeys(object, function)
: returns the first key that passes the requirements of the function parameter -
findKeysByValue(object, string)
: returns the first key of which it's value matches the value parameter -
eqArrays(array, array)
: returns whether the array parameters are equal or not -
eqObjects(object, object)
: returns whether the object parameters are equal or not -
assertEqual(value, value)
: logs to the console an assert message whether the primitive value parameters are equal -
assertArraysEqual(array, array)
: logs to the console an assert message whether the array parameters are equal -
assertObjectsEqual(object, object)
: logs to the console an assert message whether the object parameters are equal
