About

Lotide is a copy of Lodash which is a modern JavaScript utility library delivering functions that makes working with arrays, strings, numbers, objects etc.. easier.

Usage

Install it:

npm install @keqingthethundercat/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

function => (inputs) => outputs

• assertEqual => (actual, expected) => true/false string comparisons
• head => (array) => returns first element in array
• tail => (array) => slices off first element and returns rest of array
• eqArrays => (arr1, arr2) => returns a boolean indicating whether arr1 is equal to arr2 in value, type and length. Can supported nested arrays
• assertArraysEqual => (arr1, arr2) => prints an assertion message to console from comparing two arrays
• without => (arr1, arr2) => arr2 is an array of values to be removed from arr1. without() returns a new array of arr1 with values of arr2 removed
• flatten => (array) => outputs a single array of elements from n-dimensional arrays
• middle => (array) => returns an array containing the middle element of the input array
• countOnly => (array, object) => returns an object containing counts of everything that the input object listed
• map => (array, callback) => returns a new array based on the results of the callback function. THe callback should take the original element, process it and then return it
• countLetters => (string) => returns a count of each of the letters in that sentence
• letterPositions => (string) => returns all the indices (zero-based positions) in the string where each character is found
• findKeyByValue => (object, value) => scans the object and returns the first key which contains the given value
• eqObjects => (object1, object2) => compares primitive, array and objects. Returns true if both objects are equal; otherwise, returns false. This is a recursive function
• assertObjectsEqual => (object1, object2) => compares two objects and returns an assertion message
• takeUntil => (array, callback) => returns a slice of the array with elements taken from the beginning until the callback returns a truthy value
• findKey => (object, callback) => scans the object and returns the first key for which the callback returns a truthy value
