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 @esra-saatci/lotide

Require it:

const _ = require('@esra-saatci/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(actual, expected): asserts whether two values are identical.
• head(array): returns the first element in the array.
• tail(array): returns a new array except the first element of the array.
• eqArrays(array1, array2): returns true if two arrays are identical and false otherwise.
• assertArraysEqual(actual, expected): returns true if two arrays are equal and false otherwise.
• without(array, itemsToRemove): returns only the items from the source array that are not in the itemsToRemove array.
• flatten(array): takes in an array that contains elements including nested array of elements and returns a flattened version of the array.
• middle(array): takes in an array and returns middle most element of the array.
• countOnly(array, itemsToCount): takes in a collection of items and returns a specific subset of those items.
• countLetters(string): takes in a sentence and returns a count of each of the letters in the sentence.
• letterPositions(string): takes in a string and returns all indices of letter positions in the string.
• findKeyByValue(object, value): takes in an object and a value and returns the first key that corresponds to that value.
• eqObjects(object1, object2): returns true if two objects are equal and false otherwise.
• assertObjectsEqual(object1, object2): asserts whether two objects are identical.
• map(array, callback): returns a new array based on the results of the callback on each item in the array.
• takeUntil(array, callback): returns a slice of the array based on the criteria specified in the callback.
• findKey(object, callback): returns the first key that meets the criteria specified in callback.
