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 @irha/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

• assertEqual(actual, expected): Checks if the two primitive values are equal and outputs the appropriate message.
• assertArraysEqual(actual, expected): Checks if the two arrays are equal and outputs the appropriate message.
• assertObjectsEqual(actual, expected): Checks if the two objects are equal and outputs the appropriate message.
• eqArrays(actual, expected): Checks if the two arrays are equal.
• eqObjects(actual, expected): Checks if the two objects are equal.
• countLetters(phrase): Counts the number of times each letter occurs in the given phrase.
• countOnly(allItems, itemsToCount): Counts the number of occurences in an array (allItems) of items denoted true in an object (itemsToCount).
• letterPositions(sentence): Finds the indices of each letter found in the phrase.
• findKey(object, callback): Finds the first key that satistfies the callback function.
• findKeyByValue(object, value): Finds the first key that has the given value.
• flatten(array): Flattens the given (nested) array.
• head(array): Returns the head (ie. first item) of the array.
• middle(array): Returns the middle of the array.
• tail(array): Returns the tail (ie. all but the first element) of the array.
• takeUntil(array, callback): Returns items of an array until the callback function is satisfied.
• without(array, itermsToRemove): Removes the specified items from an array.
• map(array, callback): Returns an array with each element from original array modified by callbackFunction.
