How to write a comparison operator correctly?

Question

JavaScript

// so the state changes, but it is necessary that it does not change, but I'm stupid

constructor(props) {
        super();
        this.state = {
            gameBoard: arr,
            turn: 'X',
            player: 0,
            connect: 'disabled',

        }
    }
    updateBoard(loc) {
if(this.state.player = 1){ // так state меняется а нужно чтобы не менялось но я туплю
                this.setState({ turn: '0' });
            } else if (this.state.player = 2){
                this.setState({ turn: 'X' });
            }
}
