SetPrototypeOf is a minimalistic, cross-platform npm package that serves as a polyfill for Object.setPrototypeOf
. This package provides a function that allows you to set the prototype of an object after the object has been created -- a feature that is supported across all modern browsers and at least dating back to IE8. In other words, it allows you to dynamically add new properties or methods to the prototype of an existing object, enhancing the object's functionalities dynamically.
To use SetPrototypeOf in your project, you must first install it via npm command npm install --save setprototypeof
. After installation is complete, you can import it in your JavaScript files using the require
keyword, or for TypeScript, use the import
keyword. Here's a quick JavaScript example:
// Require the module
var setPrototypeOf = require('setprototypeof');
// Initialize an object
var obj = {};
// Use setPrototypeOf to add new functionalities to the object's prototype
setPrototypeOf(obj, {
foo: function () {
return 'bar';
}
});
// Call the newly added function
console.log(obj.foo()); // Outputs: bar
And for TypeScript:
// Import the module
import setPrototypeOf from 'setprototypeof';
After importing, you can use it exactly as shown in the JavaScript example.
The documentation for SetPrototypeOf resides in the README file of its GitHub repository. The readme file contains all the necessary information about what the package does and how to use it. For additional queries or in-depth exploration, you should refer to the official JavaScript documentation on Object.setPrototypeOf
, as SetPrototypeOf is essentially a polyfill for it. You can access the SetPrototypeOf's GitHub repository at the following URL: https://github.com/wesleytodd/setprototypeof.
