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 @karamvir-bains/lotide
Require it:
const _ = require('@karamvir-bains/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
head(array)
: Takes in an array and returns the first element in the array.tail(array)
: Takes in an array and returns everything but the first element in the array.eqArrays(array1, array2)
: Reclusively checks both arrays and returns true if they match or false if they don't.without(array1, array2)
: Takes in 2 arrays, an original array (array1) and an array with items to remove (array2). Returns a new array with all the original values excluding the removed values.flatten(array)
: Takes in an array that has nested arrays, and returns an array with all the same values but no nested arrays.middle(array)
: Takes in an array and returns elements that are closest to the middle of an array.countOnly(array, object)
: Takes in an object and counts the number of times a given object value appears in the array and returns an object of those counted values, if the value was not in the array returns undefined for the key value.countLetters(string)
: Takes in a string and returns a object with an count of each letter in the stringletterPositions(string)
: Takes in a string, and returns an array of indexes for each letter in an objectfindKeyByValue(object, value)
: Takes in an object and a value, if the value is associated with a key it returns the key, otherwise undefinedeqObjects(object1, object2)
: Reclusively checks if both objects have identical keys with identical values. Returns true if they match or false if they don't.map(array, callback)
: Takes in an array, loops through each item and applies the callback function requirements. Returns an array with the changes.takeUntil(array, callback)
: Takes in an array, and returns everything in the array until callback function returns false.findKey(object, callback)
: Takes in an object and a callback. If the callback function returns true return the associated key, otherwise undefined.
