How to send post request json to javascript and get it to php?
Sending data not through a form, but by a condition, for example, if(){}
It is necessary on pure js, without jquery
Thanks in advance

const url = 'https://example.com/profile';
const data = { username: 'example' };

try {
  const response = await fetch(url, {
    method: 'POST', // или 'PUT'
    body: JSON.stringify(data), // данные могут быть 'строкой' или {объектом}!
    headers: {
      'Content-Type': 'application/json'
    }
  });
  const json = await response.json();
  console.log('Успех:', JSON.stringify(json));
} catch (error) {
  console.error('Ошибка:', error);
}
