[@react.component]
let make = (~name) => name -> React.string;

// If you want to shallow compare the props then use React.memo
let make = React.memo(make);

// If you want to custom compare the nested props then use React.memoCustomCompareProps
let deepCompare = (nextProps, currentProps) => nextProps === currentProps;

let make = React.memoCustomCompareProps(
  make,
  (nextProps, currentProps) => {
    let result = deepCompare(nextProps, currentProps);
    result;
  }
);

If you getting error like This expression's type contains type variables that can't be generalized try to give your props types in the function definition like

let make = (~name: string) => name -> React.string;
