Install it:

npm install @dave4174/lotide

const _ = require('@dave4174/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual([],[]): Assertion utility to check for equivalence between two arrays.
• assertEqual(x,y): Assertion utility to check if two primitive types are equal.
• assertObjectsEqual({},{}): Assertion utility to check for equivalence between two arrays.
• countLetters(''): Counts the number of occurrences of each letter in a string.
• countOnly([],{}): Counts the occurrences of items in an array of strings. The strings to count are determined by the second object paramter.
• eqArrays([],[]): Returns true or false depending on whether two arrays are equivalent.
• eqObjects({},{}): Returns true or false depending on whether two objects are equivalent.
• findKey({},func()): Returns the first key from an object that satisfies a callback function.
• findKeyByValue({},''): Returns a key from an object based on the value associated with that key.
• head([]): Returns the first item from an array.
• letterPositions(''): Returns all the zero-based index positions of all letters in a string.
• map([],func()): Returns an array of transformed items based on a callback function.
• middle([]): Returns the middle item of an array with an odd number of items, or the middle two items from an array with an even number of items.
• tail([]): Removes the first item from an array and returns the remaining items as an array.
• takeUntil([],func()): Returns an array that consists of all the first items of an array up until the item which satisfies a callback function.
• without([],[]): Returns an array with items removed which exist in a second array.
