Available Functions

concat

Concatinates all given array and return it.

let arr=[4]
let result =funcwizard.concat([1,2,3],arr,[5])//result will be [1,2,3,4,5]

chunk

Divides the array into blocks of given number and return it.

let result =funcwizard.chunk(['a', 'b', 'c', 'd'], 3)//result will be [["a", "b", "c"], ["d"]]
let result =funcwizard.chunk(['a', 'b', 'c', 'd'], 2)//result will be [["a", "b"], ["c", "d"]]

initial

Gets all but the first element of array

let result =funcwizard.initial(['s','w', 'b', 'c', 'd','e'])//result will be ["w", "b", "c", "d", "e"]

indexof

Find the index of the given number and also give optional parameter to specify from where the search should start.

let result =funcwizard.indexof([1,0,2, 1, 2], 2) //result will be 2
let result =funcwizard.indexof([1,0,2, 1, 2], 2,3) //result will be 4

join

Gets an array and joins then with any string inbetween each element of the array and returns a string.

let result =funcwizard.join([1,0,2, 1, 2], "~") //result will be "1~0~2~1~2"
let result =funcwizard.join(['a', 'b', 'c'], "&") //result will be "a&b&c"

last

Returns the last element of the array

let result =funcwizard.last([1, 2, 3,4]) //result will be 4

nth

Returns the element in the given position

options

• positive position-returns from the start
• negative position-returns from the end

let array = ['a', 'b', 'c', 'd'];
let result =funcwizard.nth(array, 1) //result will be 'b'
let result1 =funcwizard.nth(array, -1) //result will be 'd'

sum

Returns the sum of the array

let result=funcwizard.sum([1,2,3]); //result will be 6

min

Returns the minimum value in an array

let result=funcwizard.min([4, 2, 8, 6]); //result will be 2
let result=funcwizard.min([]); //result will be 'undefined'

max

Returns the maximum value in an array

let result=funcwizard.max([4, 2, 8, 6]); //result will be 8
let result=funcwizard.max([]); //result will be 'undefined'

size

Returns the size of object,array and string.

let result=funcwizard.size([1, 2, 3]); //result will be 3
let result=funcwizard.size({ 'a': 1, 'b': 2 }); //result will be 2
let result=funcwizard.size('pebbles'); //result will be 7

deepcopy

Copy an object by value for nested objects and not by reference with this function

let result=funcwizard.deepcopy({ 'a': 1, 'b': {'c':2} }); //result contained copy of the object without same reference.

dropright

Removes the given number of elements from the end of the array Default value to remove is 1

let result=funcwizard.dropright([1,2,3,4]); //result will be [1,2,3]
let result=funcwizard.dropright([1,2,3,4],0); //result will be [1,2,3,4]
let result=funcwizard.dropright([1,2,3,4],2); //result will be [1,2]
let result=funcwizard.dropright([1,2,3,4],5); //result will be []

dropleft

Removes the given number of elements from the start of the array Default value to remove is 1

let result=funcwizard.dropright([1,2,3,4]); //result will be [2,3,4]
let result=funcwizard.dropright([1,2,3,4],0); //result will be [1,2,3,4]
let result=funcwizard.dropright([1,2,3,4],2); //result will be [3,4]
let result=funcwizard.dropright([1,2,3,4],5); //result will be []

dropboth

Removes the given number of elements from both starting and ending of the array. Default value to remove is 1

let result=funcwizard.dropboth([1,2,3,4,5,6]); //result will be [2,3,4,5]
let result=funcwizard.dropboth([1,2,3,4,5,6],0); //result will be [ 1, 2, 3, 4, 5, 6 ]
let result=funcwizard.dropboth([1,2,3,4,5,6],2); //result will be [3,4]
let result=funcwizard.dropboth([1,2,3,4,5,6],5); //result will be []
