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

Call it:

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

• assertObjectsEqual(actual, expected): Returns whether two objects are same and log the result.
• countLetters(text): Count the number of letters and return as an object.
• countOnly(allItems, itemsToCount): Count the number of letters within a specific set and return as an object.
• eqArrays(actual, expected): Returns whether two arrays are same.
• eqObjects(object1, object2): Returns whether two objects are same.
• findKey(object1, callback): Finding the key within an object according to the result returned by the callback function.
• findKeyByValue(object, value): Finding the key within an object according to the value of it.
• flatten(array): Flatten multi-dimension array into a one-dimension array.
• head(array): Return the first variable of an array.
• letterPositions(sentence): Flatten multi-dimension array into a one-dimension array.
