How To Use Contexts in Go — step-by-step Programming tutorial on Progressive Robot

How To Use Contexts in Go

When developing a large application, it can be helpful for a function to know more about the environment it’s being executed in aside from the information needed for a function to work on its own. To help with this, Go includes a context package in its standard library. Learn to create a Go program that uses a context within a function. You’ll also store additional data in the context and retrieve it from another function. Finally, you’ll explore methods for ending a context.

How To Create Wrapper Components in React with Props — step-by-step Javascript tutorial on Progressive Robot

How To Create Wrapper Components in React with Props

In this tutorial, you’ll create wrapper components with props using the React JavaScript library. Wrapper components are components that provide a default structure to display the child components. This pattern is useful for creating user interface (UI) elements that are used repeatedly throughout a design, like modals, template pages, and information tiles. You’ll use the rest and spread operators to collect unused props to pass down to nested components.
