En lugar de usar la forma original como this.state , quiero usar la cadena combinada.

 import React, { Component } from "react"; class Test extends Component { constructor(props) { super(props); this.state = { Monday100: "Monday100", }; } render() { let day = "Monday"; let number = "100"; let dayAndNumber = day + number; return ( <div> {/* I Want To Do It Like This */} {/* {this.state.dayAndNumber} */} {/* Original Way */} {this.state.Monday100} </div> ); } } export default Test;
