Package Exports
- args-to-arr
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (args-to-arr) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Node.js
const toArray = require("args-to-arr");
const array = toArray(arrayLike, start);Browser
After adding the script tag, toArray function will be available globally.
const array = toArray(arrayLike, start);Reference
example
import toArray from "args-to-arr";
function anything(firstArg) {
// convert arguments to array
// starting from argument 1
// it won't include firstArg
const args = toArray(arguments, 1);
// do something with the array
}syntax
toArray<T>(arr: ArrayLike<T>, start: number = 0): T[];return
type: Array
It returns a new array based on the provided parameters.
arr
type: Array | ArrayLike
Array or Array-like object to be converted to a new array.
start
type: number
default: 0
Index number for array convertion to start from. If not provided or it equals null or undefined it will default to 0.
Providing a negative start index will cause the function to start iterating X items from the end of the array, see the following example.
example
const array = toArray([1, 2, 3, 4], -2);
console.log(array);[ 3, 4 ]If the provided negative start index exceeds the size of the array, it will fill the begining of the resulting array with empty values.
example
const array = toArray([1, 2], -4);
console.log(array);[ <2 empty items>, 1, 2 ]
