If you do not have npm installed, you can download it here .
EXAMPLE CODE:
const array = require('simplifying');
let arr = [2, 3, 4, 3, 3, 2, 4];
console.log(array.removeDuplicates(arr));
//OUTPUT: [2, 3, 4]
List of all methods on array:
| Method | Parameters | Use |
|---|---|---|
| shuffle | array: Array | Shuffles array and returns it |
| removeDuplicates | array: Array | Removes all duplicate elements and returns a new array |
| pickRandom | array: Array, n: Number, unique?: Boolean |
Returns an array of n random elements from array. The returned elements will be unique if true is passed in the third parameter |
| countItem | array: Array, 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 |
| swapByPosition | array: Array, pos1: number, pos2: number |
Swaps values in pos1 and pos2 in the array |
| 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, value: string |
Deletes an item based on the (key, value) pair |
| getKeys | array: Array | Returns an array of all the keys inside the object. Assumes that all objects have the same keys |
| findObjects | array: Array, func: Function |
Executes the function on all objects and returns the satisfied objects |
