PropTypes

PropTypes are a way in React (a JavaScript library for building user interfaces) to check that the data passed between components is of the correct type. Think of them as validation rules that help developers catch mistakes early by ensuring, for example, that a text label is passed as a string or a list of items as an array. This validation improves code reliability and makes debugging easier. PropTypes are especially useful in large applications or teams, where different parts of the code need to agree on the kind of data they exchange.
