HTML Preparation code:

Script Preparation code:

function ComponentWithOuterFunctionUseCallback() {
  function functionToTest(evt) {
	evt.preventDefault();
  }
  const testFunction = React.useCallback(functionToTest, []);
  return React.createElement('button', {onClick: testFunction}, 'Test click');
}

function ComponentWithUseCallback() {
  const testFunction = React.useCallback(evt => evt.preventDefault(), []);
  return React.createElement('button', {onClick: testFunction}, 'Test click');
}

function ComponentWithInlineFunction() {
  function testFunction(evt) {
    evt.preventDefault();
  }
  return React.createElement('button', {onClick: testFunction}, 'Test click');
}

function ComponentWithArrowFunction() {
  const testFunction = (evt) => {
    evt.preventDefault();
  }
  return React.createElement('button', {onClick: testFunction}, 'Test click');
}

 const testFunction = (evt) => {
    evt.preventDefault();
 }

function ComponentWithOutsideArrowFunction() {

  return React.createElement('button', {onClick: testFunction}, 'Test click');
}
