React: Mutating Props - Clone Instead

    // Below is an example to incorrectly mutate the styles
    var svgStyle = styles.svg;
    svgStyle.width = this.state.width;
    svgStyle.height = this.state.height;
		
    // Below is a proper way to change the style that is used by cloning the style rather than mutating it
    var svgStyle = {...styles.svg, width: this.state.width, height: this.state.height }
