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 @hsmalhi94/lotide
Require it:
const _ = require('@hsmalhi94/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(actual, expected)
: uses eqArrays to check if two arrays are equal and prints messages -
assertEqual(actual, expected)
: checks if two values are equal -
assertObjectsEqual(actual, expected)
: uses eqObjects to check if two objects are equal and prints messages -
countLetters(str)
: returns the count of each letter in a string -
countOnly(allItems, itemsToCount)
: returns the count of each letter in a string, but only for the letters specified -
eqArrays(arr1, arr2)
: checks if two arrays are equal -
eqObjects(object1, object2)
: checks if two objects are equal -
findKey(object, callback)
: returns the key of a given object, if the key's value satisfies the callback function -
findKeyByValue(object, value)
: finds a key based on the value passed -
flatten(arr)
: flattens a nested array -
head(arr)
: returns the head of an array (first element) -
middle(arr)
: returns the middle of an array (one or two elements) -
tail(arr)
: returns the tail of an array -
letterPositions(sentence)
: returns an object where the keys are the letters in a string and the values are the indexes at which those letters appear -
map(array, callback)
: based on the callback function provided, performs the function on each element of an array and returns a new array -
takeUntil(array, callback)
: returns all items from a provided array until the callback provided returns a truthy value -
without(source, itemsToRemove)
: returns an array without the items that were specified in the itemsToRemove parameter
