React native Array Sort problem when 2 array are the same value

I have a problem when I using the array sort function

I have 2 state value are saving the same array value, (devName and devNameSort)

I want to sorting the one of the array and try to get the index on the original array.
However, when I sorting the array "devNameSort", the "devName" would be changed together.
Would any method to fix the problem

The Value of
dev  = ["08d5", "151e", "d467", "0655", "a853"]
devName = ["W1", "W4", "W2", "W3", "W0"]
devNameSort = ["W1", "W4", "W2", "W3", "W0"]

 this.state = {
            dev: this.props.route.params.dev,
            devName: this.props.route.params.devName, 
            devNameSort: this.props.route.params.devNameSort,
  }



    componentDidMount() {
        const sd = this.state.dev
        const sdn = this.state.devName
        console.log(sd);
        console.log(sdn);
        setTimeout( ()=> {
            const sdbs = this.state.devSort;
            console.log(sdn);
            sdbs.sort().map( (bs,index) => {
                const sdIndex = sdn.indexOf(bs)
                console.log(bs,":",index, sdIndex)
                console.log(sd[sdIndex])

            })
        }, 1000);
}

I updated the code as const a copy, but it not work too

        const sdn = this.state.devName
        const sdCopy = this.state.devName
        console.log("Orginal - before sort", sdn);
        sdn.sort()
        console.log("Orginal", sdn);
        console.log("Copy", sdCopy);

 LOG  Orginal - before sort ["W4", "W1", "W3"]
 LOG  Orginal ["W1", "W3", "W4"]
 LOG  Copy ["W1", "3", "W4"]

I Find the solution, but don’t understand why it work.

const sdn = this.state.devName 
const sdCopy = JSON.parse(JSON.stringify(sdn))
sdCopy.sort().map((bs,index) => {
                const sdIndex = this.state.devName.indexOf(bs)
                console.log(bs,":",index, sdIndex)
                console.log(sd[sdIndex])
            })
