Selecting state object name dynamically in React JS

Quick question, how do I change an object in a copy of state that is selected using e.target.name, and then set to e.target.value. Like if i want to change newState.age when e.target.name = age is sent.

stateUpdater = (e) => {
    const newState = this.state;
    const name = e.target.name;
    const value = e.target.value;

    // How do I change newState.(name passed from target) to become the passed value;

    this.setState({newState});
  }
