Working with radio in React

Working with radio radio is a bit different from, for example, the same checkboxes. The problem is that several radios will have the same state, but different value.

Therefore, the work is done as follows: each radio button has its own value written into the value attribute, and a special condition is written into the checked attribute, which checks whether the state is equal to a certain value. If it is equal, the radio button will be checked, and if it is not, it will be unchecked.

Here is the implementation of what was described:

jsxfunction App() {
  const [value, setValue] = useState(1);
  
  function changeHandler(event) {
    setValue(event.target.value);
  }
  
  return <div>
    <input
      type="radio"
      name="radio"
      value="1"
      checked={value === '1' ? true : false}
      onChange={changeHandler}
    />
    <input
      type="radio"
      name="radio"
      value="2"
      checked={value === '2' ? true : false}
      onChange={changeHandler}
    />
    <input
      type="radio"
      name="radio"
      value="3"
      checked={value === '3' ? true : false}
      onChange={changeHandler}
    />
  </div>
}
