npm install @sandypockets/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(...): Checks if the contents of two arrays are equal, and return an assertion message.
• assertEqual(...): Returns assertion message.
• assertObjectsEqual(...): Checks if two objects contain equal contents, and returns an assertion message.
• countLetters(...): Checks the number of occurrences of each letter in a string.
• countOnly(...): Checks the number of occurrences a string (in this case a name) occurs in an array.
• eqArrays(...): Checks if two arrays are equal.
• eqObjects(...): Checks if two objects are equal.
• findKey(...): Scans the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• findKeyByValue(...): // Scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• flatten(...): Takes an array of nested arrays, and returns a single array, without any nesting.
• head(...): Returns the first element of an array.
• letterPositions(...): Returns the position of a particular letter/character.
• map(...): Vanilla JS map function. Creates a new array populated with the results of calling the function on every element in the array it is called on.
• middle(...): Returns the middle element of an array. Arrays with odd numbers return one element, while arrays with even numbers return two elements.
• reverse(...): Reverses a word.
• tail(...): Removes the head (first element) of an array, and returns the remainder of the array as is.
• takeUntil(...): The function will return a slice of the array with elements taken from the start of the array. It runs until the callback returns a truthy value.
• without(...): Removes an element (supplied by you) to remove from the array, then returns the entire array without that specific element.
