javascript - 将 Unix 时间戳转换为 API 中可读的时间

Question

我正在从 Firebase 中提取数据以在我的应用程序中绘制图表。现在图表工作正常，y 轴显示正确的数据，但 x 轴显示 unix 时间戳，因为这就是我的数据数组所具有的内容，如何在绘制图表之前将其转换为可读时间？我研究过 moment.js，但我不确定在哪里应用它。

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
        words: [],
      options: {
              chart: {
              },   
              legend: {
                position: 'top',
                horizontalAlign: 'right',
                floating: true,
                offsetY: -25,
                offsetX: -5
              }
            },
    };
  };


  componentDidMount() {
  this.renderCharts();
  };

  renderCharts() {
    const wordRef = firebase.database().ref('MyFireBaseDB');
    wordRef.on('value', (snapshot) => {
      let words = snapshot.val();
      let myState = [];
      for (let word in words) {
        myState.push({
          x: word, ///This is grabbing the Unix timestamps from database///
          y: words[word], ///My y-axis data points///
        })
      }
  this.setState({
    arr: myState,
  })
  });
  }

render() {
      const series = [{
      name: "Chart Data",
      data: this.state.arr
  },
  ];

                        return (
                  <div className='App'>

  <Chart options={this.state.options} series={series} type="line" width={'100%'} height={320} />

                  </div>


              );

      }
  }

这是数据数组的样子，现在图表工作正常，但 X 轴显示 unix 时间戳，如何在绘制图表之前将其转换为可读时间？

[{"x":"1574342743","y":196},{"x":"1574343390","y":176},{"x":"1574344052","y":121},{"x":"1574344721","y":114}]

Answer 1

var timestamp = "0"; //string timestamp 
var d = new Date(+timestamp); //cast to int
console.log(d.toLocaleString());
//1970-01-01T00:00:00.000Z
