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

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(string): Extracts letters from a string and puts them into a object as the keys. Then, counts the number of times that letter is found in a string and adds them as the value of the keys.
• countOnly(allItems, itemsToCount): Counts the items that are marked true in itemsToCount(object) in allItems(array).
• findKey(object, callback): Search for key by callback function.
• findKeyByValue(object, value): Search for key by value.
• flatten(array): Takes the values from an array and the values inside nested arrays inside that array and pushes them to a new single array with only values inside (no nested arrays).
• head(array): Returns the value at 0 index position in an array.
• letterPositions(sentence): Moves string letters into an object where the key is the letter and the value is the index position(s) that letter is found in the string.
• map(array, callback): Uses a callback function to determine which values in an array are pushed to new array.
• middle(array): Returns the middle value(s) inside of an array.
• tail(array): Returns all values except the 0 index position in an array.
• takeUntil(array, callback): Pushes values from a provided array to a new array until the callback provided returns a truthy value.
• without(source, itemsToRemove): Takes a source array and an array with values to remove. If any of the values from itemsToRemove are found in source, return newArray with out values those values.
• eqArrays(arr1, arr2): Checks if two arrays are the same.
• eqObjects(object1, object2): Checks if two objects are the same.
