access value inside this.state in react

I have the following line of codes.

constructor(props) {
        super(props);
        this.state = {
            trends_1: [
                { start: [parseFloat(props.ab), parseFloat(props.cd)], end: [parseFloat(props.wy), parseFloat(props.yz)], appearance: { stroke: "green" }, type: "XLINE" }
            ]
        };
    }

How can I access the value of parseFloat(props.ab) and parseFloat(props.yz)?

You can access it with index position

this.state.trends_1[0].start[0]
this.state.trends_1[0].start[1]

this.state.trends_1[0].end[0]
this.state.trends_1[0].end[1]

You have to access like this.

let ab = this.state.trends_1[0].start[0];
let cd = this.state.trends_1[0].start[1];
