This project was created and published by me as part of my learnings at Lighthouse Labs.

Usage

Install it:

npm install @fbssaejun/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(...): returns the first element from the input array.
• tail(...): returns the "tail" of an array, everything except for the first item of the input array.
• middle(...): returns the middle-most element(s) of the given array.
• countLetters(...): take in a sentence(string) and return a count of each of the letters in that sentence into an object.
• flatten(...): take in an array containing nested arrays, and return a single array with all the elements in the array.
• without(...): returns a subset of a given array, removing specific elements(specified from the input argument).
• map(...): return a new array based on the results of the callback function.
• letterPositions(...): return all the indices in the string where each character is located.
• findKey(...): takes in an object and a callback function. Looks through the object, and returns the value of what the callback function is looking for.
• findKeyByValue(...): takes in an object and a value. It looks through the object and returns the first key that contains the given value. If no key with that given value is found, returns undefined.
• takeUntil(...): returns items in the input array until the callback function's condition meets true.
• countOnly(...): returns an object of specific items (passed in as argument) from the input array.
• assertEqual(...): compare two values if they are strictly identical.
• eqArrays(...): compare two arrays if they are identical.
• eqObjects(...): compare two objects if they are identical.
• assertArraysEqual(...): asserts if two arrays are equal.
• assertObjectsEqual(...): asserts if two objects are equal.
