About error-cause
Error handling in JavaScript can often become complex and tedious, but with the npm package "error-cause", developers have a powerful tool at their disposal to manage and trace errors efficiently. This package offers an ES-spec-compliant shim/polyfill/replacement for the `.cause` property on all Error types, enhancing error handling capabilities in JavaScript applications. By using "error-cause", developers can attach a cause to any error object, which simplifies debugging by providing more context and making the root cause of errors more apparent. This is particularly useful in modern applications where processes are highly asynchronous and handling errors effectively is crucial for maintaining robustness and reliability.
To integrate "error-cause" into your JavaScript project, you can easily install it using the command `npm install error-cause`. This installation process adds the package to your project, allowing you to leverage its functionalities immediately. Once installed, "error-cause" enables you to extend native Error objects with a `cause` property, thereby adhering to the latest ECMAScript standards. This not only aligns with modern JavaScript development practices but also ensures that your error handling logic is both forward-compatible and easier to maintain.
The "error-cause" package is designed to work seamlessly across different JavaScript environments, from as old as ES3 to the latest versions, making it a versatile choice for developers working with a wide range of technologies and platforms. Its implementation promotes cleaner, more maintainable code and significantly improves the developer experience by streamlining the debugging process. For teams looking to enhance their error management practices, adopting "error-cause" can lead to more efficient problem resolution and a decrease in development time spent on tracing elusive bugs.

error-cause 
An ES-spec-compliant shim/polyfill/replacement for the .cause property on all Error types that works as far down as ES3
This package implements the es-shim API “multi” interface. It works in an ES3-supported environment and complies with the proposed spec.
Getting started
npm install --save error-cause
Usage/Examples

require('error-cause/auto');
try {
x();
} catch (e) {
const actual = new Error('a better message!', { cause: e });
assert(actual instanceof Error);
assert(actual.cause === e);
}
