componentDidMount() { this.loadData()

Question

componentDidMount() { this.loadData()

setInterval(this.loadData, 30000);
}

async loadData() {
try {
const res = await fetch('https://api.apijson.com/...');
const blocks = await res.json();
const dataPanelone = blocks.panelone;
const dataPaneltwo = blocks.paneltwo;

this.setState({
panelone: dataPanelone,
paneltwo: dataPaneltwo,
})
} catch (e) {
console.log(e);
}
}
а так нельзя?
