How to know if browser supports webSQL?

I want to detect if browser supports webSQL, in the same way we can check for indexedDB like below

if ( window.indexedDB ) {
    // indexedDB support is available
}

Modernizr only checks if "openDataBase" is available on window:

const supports_webSQL = ("openDatabase" in window);

console.log( "supported:", supports_webSQL );
