Usage

Install it:

npm install @todd-demone/lotide

Require it:

const _ = require('@todd-demone/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• _.assertArraysEqual(actual, expected): Asserts equality of two arrays, actual and expected.
• _.assertEqual(actual, expected): Asserts strict equality ( === ) of actual and expected, both of which are primitive values.
• _.assertObjectsEqual(actual, expected): Asserts equality of two objects, actual and expected.
• _.countLetters(sentence): Counts the number of times each letter in sentence occurs.
• _.countOnly(allItems, itemsToCount): Searches an array for specified items and returns a count of those items.
• _.eqArrays(array1, array2): Performs a deep comparison of two arrays to determine if they are equivalent.
• _.eqObjects(object1, object2): Performs a deep comparison of two objects to determine if they are equivalent.
• _.findKey(object, callback): Iterates over an object and returns the first key for which the callback returns a truthy value.
• _.findKeyByValue(object, value): Scans an object and returns the first key which contains the given value.
• _.flatten(array): Flattens an array a single level deep.
• _.head(array): Gets the first element of an array.
• _.letterPositions(sentence): Scans a sentence to find the index(indices) of each character in the sentence.
• _.map(array, callback): Creates a new array containing the results of calling a callback function on every element in the array.
• _.middle(array): Gets the middle element(s) of an array.
• _.tail(array): Gets all but the first element of an array.
• _.takeUntil(array, callback): Returns a slice of an array, starting at the beginning of the array and ending when the applied function returns a truthy value.
• _.without(source, itemsToRemove): Picks out items from an array, except for items that are specified in the list of itemsToRemove.
