This is a built-in template used for creating React functional components, e.g. when using the 'Extract Component' refactoring. You can customize this template, for example, to define components as arrow functions or to define prop types differently. You can also use predefined variables that will be then expanded into the corresponding values.
Predefined variables will take the following values:
${NAME}   component name
${COMPONENT_BODY}   component body
${PROP_TYPES}   props type definition
