How do I push a checkbox to an array while checkbox is by default checked

See more:

checkbox

ReactJS

handleInputChangeDom = (event) => {
  const target = event.target;
  var value = target.value;
  const Address_type = this.state.Address_type;

  if (event.target.checked) {
    Address_type.push(event.target.value);
  } else {
    let index = Address_type.indexOf(event.target.value);
    Address_type.splice(index, 1);
  }

  this.setState({
    Address_type: Address_type,

  });
};

What I have tried:
