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 @falcre/lotide

Require it:

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

Call it:

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

• 'assertObjectsEqual(actual, expected)' : compares two objects and logs indication message to the console.
• 'countLetters(string)' : counts the number of letters in a string and returns an object with the count.
• 'countOnly(allItems, itemsToCount)' : counts the number of times an item appears in an array and returns .an object with the count.
• 'eqArrays(array1, array2)' : compares two arrays and returns true if they are equal.
• 'eqObjects(object1, object2)' : compares two objects and returns true if they are equal.
• 'findKey(object, callback)' : returns the first key for which the callback returns a truthy value.
• 'findKeyByValue(object, value)' : returns the first key for which the value is found.
• 'flatten(array)' : flattens nested array into a single-level array.
• 'head(array)' : returns the first element of an array.
• 'letterPositions(string)' : returns an object with the index of each letter in a string.
• 'map(array, callback)' : returns a new array based on the results of the callback function.
