item: any
Returns the frequency of the passed item in the array
countAll array: Array Returns a map which holds the frequencies of all items in the array
searchItems array: Array,
item: any
Returns all positions where the given item is found
removeItems array: Array,
item: any
Deletes multiple occurances of the given item
toArray x: (string, number) Converts string or number to array of characters or digits
merge array1: Array,
array2: Array,
type?: string
Merge two arrays.
type == 'merge-all': Keep the duplicates
type == 'common': Returns common elements
no type: Merge and remove common
clean array: Array Removes null, undefined, '', NaN
flatten array: Array Flattens all nested arrays inside

swapByValues array: Array,
value1: any,
value2: any
Swaps value1 and value2 in the array
perform array: Array,
operation: string
Performs the said operation on the array.
Allowed Operations:
sum, product, min, max, average
arrayToObject array: Array Converts an array to object
slide array: Array,
steps: number,
direction?: string
Shifts array by n steps in the given direction. The default direction is left.
range array: Array,
start: number,
end: number
Returns a subarray from start to end - 1

List of all methods on array of objects:

Method Parameters Use
arrayOfObjectsToObject array: Array,
keyField: string
Converts an array of objects to an object where key is keyField
sortByKeyField array: Array,
keyField: string,
order?: string
Sorts an array of objects based on keyField. Default sorting order is ascending. Pass 'desc' to order for reverse.
getFields array: Array,
fields: Array
Returns an array of objects containing only the required fields
getOneField array: Array,
field: string
Returns an array of all the values of the particular field
searchByKeyField array: Array,
searchField: string,
searchValue: string,
reqFields?: Array
Searches the array for the given (key, value) pair and returns only the reqFields. If nothing is passed, the whole object is returned.
deleteByKeyField array: Array,
field: string,
