Method

All the functions used in Bue is based on lodash(v4.0.0-pre), some of them have been customized(italic) in the following list.

Language Functions

• clone
  Creates a shallow clone structured clone algorithm of value.

    bue.clone(value)
  

• isArray
  Checks if value is classified as an Array object.

    bue.isArrayLike(value)
  

• isBoolean
  Checks if value is classified as a boolean primitive or object.

    bue.isBoolean(value)
  

• isDate
  Checks if value is classified as a Date object.

    bue.isDate(value)
  

• isEmpty
  Checks if value is empty. A value is considered empty unless it's an arguments object, array, string, or jQuery-like collection with a length greater than 0, an object with own enumerable properties or a number.

    bue.isEmpty(value)
  

• isFunction
  Checks if value is classified as a Function object.

    bue.isFunction(value)
  

• isLength
  Checks if value is a valid array-like length.

    bue.isLength(value)
  

• isNil
  Checks if value is null or undefined.

    bue.isNil(value)
  

• isNull
  Checks if value is null.

    bue.isNull(value)
  

• isNullOrUndefined Checks if value is null or undefined.

    bue.isNullOrUndefined(value)
  

• isNumber
  Checks if value is classified as a Number primitive or object.

    bue.isNumber(value)
  

• isInteger Checks if value is an integer.

    bue.isInteger(value)
  

• isObject
  Checks if value is the language type of Object.

    bue.isObject(value)
  

• isPlainObject
  Checks if value is a plain object, that is, an object created by the Object constructor or one with a [[Prototype]] of null.

    bue.isPlainObject(value)
  

• isPresent
  Check if value is not Empty

    bue.isPresent(value)
  

• isRegExp
  Checks if value is classified as a RegExp object.

    bue.isRegExp(value)
  

• isString
  Checks if value is classified as a String primitive or object.

    bue.isString(value)
  

• isUndefined
  Checks if value is undefined.

    bue.isUndefined(value)
  

Array Functions

• compact
  Creates an array with all falsey values removed. The values false, null, 0, "", undefined, and NaN are falsey.

    bue.compact(array)
  

• flatten
  Flattens array a single level.

    bue.flatten(array)
  

• first
  Gets the first element of array.

    bue.first(array)
  

• last
  Gets the last element of array.

    bue.last(array)
  

Object Functions

• extend
  Assigns own enumerable properties of source objects to the destination object. Source objects are applied from left to right. Subsequent sources overwrite property assignments of previous sources but it iterates over own and inherited source properties.

    bue.entend(object, [sources])
  

• get
  Gets the value at path of object. If the resolved value is undefined the defaultValue is used in its place.

    bue.get(object, path, [defaultValue])
  

• hasIn
  Checks if path is a direct or inherited property of object.

    bue.hasIn(object, path)
  

• keys
  Creates an array of the own enumerable property names of object.

    bue.keys(object)
  

• keysIn
  Creates an array of the own and inherited enumerable property names of object.

    bue.keysIn(object)
  

• values
  Creates an array of the own enumerable property values of object.

    bue.values(object)
  

String Functions

• pad
  Pads string on the left and right sides if it's shorter than length. Padding characters are truncated if they can't be evenly divided by length.

    bue.pad([string=''], [length=0], [chars=' '])
  

• padLeft
  Pads string on the left side if it's shorter than length. Padding characters are truncated if they exceed length.

    bue.padLeft([string=''], [length=0], [chars=' '])
  

• padRight
  Pads string on the right side if it's shorter than length. Padding characters are truncated if they exceed length.

    bue.padRight([string=''], [length=0], [chars=' '])
  

• escapeRegExp Escape RegExp special characters.

    bue.escapeRegExp([string=''])
  

Collection Functions

bue.iteratee: a function that a invokes func with the arguments of the created function.

• each
  Iterates over elements of collection invoking iteratee for each element. The iteratee is invoked with three arguments: (value, index|key, collection). Iteratee functions may exit iteration early by explicitly returning false.

    bue.each(collection, [iteratee = bue.identity])
  

• eachRight
  This method is like bue.each except that it iterates over elements of collection from right to left.

    bue.eachRight(collection, [iteratee = bue.identity])
  

• map
  Creates an array of values by running each element in collection through iteratee. The iteratee is invoked with three arguments: (value, index|key, collection).

    bue.map(collection, [iteratee = bue.identity])
  

Math Functions

• max
  Computes the maximum value of array. If array is empty or falsey undefined is returned.

    bue.max(array)
  

• min
  Computes the minimum value of array. If array is empty or falsey undefined is returned.

    bue.min(array)
  

Assertion Testing

• assert The assert module provides a simple set of assertion tests that can be used to test invariants, based on nodejs core module assert
