Benchmark: Optional chaining test

Script Preparation code:

var myConfig = {
	config: {
		exp: 1000,
	}
}

var myEmptyConfig = {
	config: {
	}
}

Tests:

Optional chaining
if (!('config' in myConfig)) return; if (myConfig?.config?.exp) { console.log( myConfig?.config?.exp * 1000 ); }
Var reuse
const config = myConfig?.config; if (!config) return; if (config.exp) { console.log( config.exp * 1000 ); }
Empty config chaining
if (!('config' in myEmptyConfig)) return; if (myEmptyConfig?.config?.exp) { console.log( myEmptyConfig?.config?.exp * 1000 ); }
Empty config var reuse
const config = myEmptyConfig?.config; if (!config) return; if (config.exp) { console.log( config.exp * 1000 ); }
