Script Preparation code:

function ComponentSpreading() {
  const onClick = evt => evt.preventDefault();
  const someText = "text";
  const someArray = ['1','2','3'];
  return React.createElement('button', [{...{ someArray, someText, onClick}}], 'Click me!');
}
                                        
function ComponentExplicit() {
  const onClick = React.useCallback(evt => evt.preventDefault(), []);
  const someText = "text";
  const someArray = ['1','2','3'];
  return React.createElement('button', [{ someArray },{ someText },{ onClick }], 'Click me!');
}

function ComponentComboSpreading() {
  const rest = { test: '1', speed: '2', component: '3' };
  const onClick = React.useCallback(evt => evt.preventDefault(), []);
  const someText = "text";
  const someArray = ['1','2','3'];
  return React.createElement('button', [{...{ ...rest, someArray, someText, onClick}}], 'Click me!');
}

function ComponentComboExplicit() {
  const rest = { test: '1', speed: '2', component: '3' };
  const onClick = React.useCallback(evt => evt.preventDefault(), []);
  const someText = "text";
  const someArray = ['1','2','3'];
  return React.createElement('button', [{...rest},{ someArray },{ someText },{ onClick }], 'Click me!');
}

Tests:
