The Unpaid Backbone of Open Source: Solo Maintainers Face Increasing Security Demands
Solo open source maintainers face burnout and security challenges, with 60% unpaid and 60% considering quitting.
The 'sliced' npm package is a utility that provides a simple way to slice arrays and array-like objects. It is particularly useful for converting arguments objects into arrays and for slicing arrays in a concise manner.
Slicing Arrays
This feature allows you to slice an array from a start index to an end index. In this example, the array [1, 2, 3, 4, 5] is sliced from index 1 to index 3, resulting in [2, 3].
const sliced = require('sliced');
const array = [1, 2, 3, 4, 5];
const result = sliced(array, 1, 3);
console.log(result); // Output: [2, 3]
Slicing Arguments Object
This feature is useful for converting the arguments object into an array and slicing it. In this example, the arguments object is sliced from index 1, resulting in [2, 3, 4].
const sliced = require('sliced');
function example() {
const args = sliced(arguments, 1);
console.log(args); // Output: [2, 3, 4]
}
example(1, 2, 3, 4);
The 'array-slice' package provides similar functionality to 'sliced' by allowing you to slice arrays and array-like objects. It is a lightweight alternative and can be used in the same scenarios where 'sliced' is used.
Lodash is a popular utility library that provides a wide range of functions for manipulating arrays, objects, and other data types. It includes a 'slice' function that offers similar functionality to 'sliced', but also provides many other utilities, making it a more comprehensive solution.
Underscore is another utility library that offers a variety of functions for working with arrays, objects, and other data types. It includes a 'rest' function that can be used to slice arrays and array-like objects, similar to 'sliced'.

##Usage
sliced
accepts the same arguments as Array#slice
so you can easily swap it out.
function zing () {
var slow = [].slice.call(arguments, 1, 8);
var args = slice(arguments, 1, 8);
var slow = Array.prototype.slice.call(arguments);
var args = slice(arguments);
// etc
}
npm install sliced
