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 @juliaj621/lotide

Require it:

const _ = require('@juliaj621/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: Compares actual and expected arrays and returns passed or failed.
• assertEqual: Compares expected and actual values.
• assertObjectsEqual: Compares actual and expected objects and returns passed or failed.
• countLetters: Counts the number of character occurances in a string.
• countOnly: Counts the number of times a string occurs in an array.
• eqArrays: Compares two arrays and returns a boolean if the arrays are the same/different.
• eqObjects: Compares two objects and returns a boolean if the object are the same/different.
• findKey: Takes an object and a callback. Scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue: Takes in an object and a value. It scans the object and returns the first key with the given value.
• flatten: Takes an array within an array and creates a new array merging the two.
• head: Returns the first element of an array.
• letterPositions: Returns the index in which a letter occurs in a string within an array.
• map: Returns the first letter of each element in an array of strings.
• middle: Returns the middle value (of odd) or values (if even) in an array longer than two elements.
• tail: Removes the first element in an array and returns the remaining elements in a new array.
• takeUntil: Takes an array and a callback function. Returns a new array of items occuring until the point specified by the callback functions.
• without: Takes an array and items to remove. Returns a new array without the removed items.
