JavaScipt: Pass HTML entities as function parameter

Is there any way to pass HTML entities as function parameters in JavaScript.

I am building a React app and I need to pass HTML entities from parent component to child component as a prop and then display character represented by that entity in the child component.

For example, please refer stackblitz here.

In Hello component I need to print htmlEntity received from App component as a prop and display character represented by that entity, in this case it would be symbol – ”.

How this can be achieved?

Answer

one way is to use dangerouslySetInnerHTML in react.

function createMarkup(str) {
  return {__html: str};
}

function MyComponent({str}) {
  return <div dangerouslySetInnerHTML={createMarkup(str)} />;
}

const myText = 'First &middot; Second';
<MyComponent str={myText} />}

another way is to use Unicode characters with escape notation (e.g. u0057) instead of HTML codes (·).

function MyComponent({str}) {
  return <div>{str}</div>;
}

const myText = 'First u0057 Second';
<MyComponent str={myText} />
