This project was created and published by me as part of my learnings at Lighthouse Labs.
Usage
Install it:
npm install @philteigne/lotide
Require it:
const _ = require('@philteigne/lotide');

: Returns array with callback specified adaptations made to each element of the inputted array. -
assertArraysEqual(array1, array2)
: Returns a true assertion if the two given arrays are identical, and a false assertion if they are not. -
assertEqual(value1, value2)
: Returns a true assertion if the two given values are identical, and a false assertion if they are not. -
assertObjectsEqual(object1, object2)
: Returns a true assertion if the two given objects are identical, and a false assertion if they are not. -
countLetters(string)
: Returns an object containing the counts of instances of letters in the given string. -

eqObjects(object1, object2)
: Return true if the two given objects are identical, return false if they are not. -
findKey(object, callback)
: Returns the first instance that satisfies callback in the given object. -
findKeyByValue(object, value)
: Returns the first key in the provided object that contains the input value. -
