typescript報錯：Object is possibly 'null' 請問怎麼解決？

這麼寫是不行的嗎？請問應該怎麼寫呢？

`

readonly state = {
    fold: true,
    answer: null
};

render () {
    return (
        

{ this.state.answer && this.state.answer.content }

) } `

 

最佳答案

 

readonly state: any = {
    fold: true,
    answer: null
};

如果未能解決，請移步：ts報錯：Object is possibly 'null' 詳解
