Ever wonder how Linux-based images can run on your Windows machine

Ever wonder how Linux-based images can run on your Windows machine, even though the OS dependencies are Linux, and by container architecture, a Linux-based image should run on a Linux host to share the OS with similar images?

To achieve this, Docker uses lightweight VMs like WSL 2 or LinuxKit, as the Windows kernel is incompatible with Linux-based containers. The VM is highly optimized (hence not a problem like the overhead we face while running traditional virtual machines directly).

The VM bridges networking, file sharing, and resource management to integrate seamlessly with the Windows host. For Windows containers, Docker directly uses the Windows kernel without needing a VM. This setup ensures efficient performance and compatibility for both Linux and Windows-based containers.

React is a one-way binding library. However, if you want to send a function or data from a child component to a parent component, you can use the useImperativeHandle hook.

To do this, you first define a ref in the parent component and pass it to the child component, which should be wrapped in forwardRef (although in React 19, we don't need it my bundler still have 18).

You then pass that ref to the useImperativeHandle hook, which takes three parameters: the first is the ref, the second is a callback function that returns all the values and functions you want to transfer from the child to the parent, and the third is a dependency array. If you want to send state data, include it in the dependency array so that it will return fresh values.

Below is a demo component that logs a name from the parent, which is defined in the child component.
