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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: compares two arrays and returns a message;
• assertEqual: compares primitive values and returns a message;
• assertEqualTail: compares arrays and returns a message;
• assertObjectsEqual: compares two objects and returns a message;
• countLetters: takes a string and returns an object of individual letters as keys and letter count as values(spaces excluded);
• countOnly: takes an object of items and an array of items to count, then returns an object with specified items counted;
• eqArrays: compares arrays and returns true or false;
• eqObjects: verifies if two objects are arrays, compares those that are not and returns true or false;
• findKey: takes a callback function and an object, and returns the first key that matches the function requirement;
• findKeyByValue: takes an object and a value, then returns the first key in the object that matches the value;
• flatten: takes an array with array values and returns a new array with the same values unpacked from array brackets(works on one level only);
• head: returns the first value of an array;
• letterPositions: takes a string and returns an object of letters with an array of indices where they occured(spaces excluded);
• map: takes a callback function and a string, and returns an array of first letters of the string;
• middle: takes an array and returns a new array with the middle array value(s);
• tail: takes an array and returns the array without the first value;
• takeUntil: takes an array and a callback function and returns a new array cut at the requested value;
• without: takes an array of items to examine and an array of items to remove, then returns a new array with the values that pass the test.
