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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): asserts if two arrays are equal;
• assertEqual(val1, val2): asserts if two values are equal;
• assertObjectsEqual(object1, object2): asserts if two objects are equal;
• countLetters(string): takes an input string and returns an object containing the characters used and frequency of use;
• countOnly(array, object): returns the count of elements from the array ONLY if they are truthy in the object;
• eqArrays(array1, array2): returns true if input arrays are equal;
• eqObjects(object 1, object2): returns true if input objects are equal;
• findKey(obj, callback): returns the key of the object selected by the callback function;
• findKeyByValue(object, value): returns the key of the object that matches the supplied value;
• flatten(array): returns a single array of values from an array containing values and/or arrays of values;
• head(array): returns the first value of an array;
• letterPositions(string): returns an object with the index position of each character in the string;
• map(array, callback): performs the callback function on each element of the array and returns a new array;
• middle(array) returns the middle value(s) from an array of at least three elements;
• tail(array) returns all but the first element of the input array;
• takeUntil(array, callback) iterates over supplied array until callback condition is met and returns a new array of all elemtns until that point;
• without(array1, array2) returns a new array of items that exist in array1 and NOT in array2;
