If you know the basics of React and have at least an idea about what the children prop in React is, this article is for you. In this article, weâll look at a React utility which lets us prepare the children prop for inspection and iteration, some of its shortcomings and how to overcome them - through a small open-source package, to keep our React code function the way it is deterministically supposed to behave, keeping performance intact. In those cases inspecting how the children prop looks like becomes essential. But in some cases, we want to inspect the children prop to maybe wrap each child in another element/component or to reorder or slice them. In the majority of cases, there is no need to understand how the children prop looks like. The most obvious and common prop that developers work with within React is the children prop. In particular, we will deep dive into one of the utility methods,, that React gives us, which helps to iterate over the children in a way which ensures performance and determinism. In this article, weâll discuss and learn about the use case of iterating over React children and the ways to do it.
