Benchmark: JS: Getter/Setter vs Direct Access Performance

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

const existingA = 'truthy-value';
const existingB = undefined;
class Env {
   get a() {
      return existingA || 'a-default-value';
   }
   get b() {
      return existingB || 'b-default-value';
   }
}
const env = new Env();
const config = {
   c: 'c-value',
};

Tests:

access existing value
function a() { return env.a; } const aReading = a();
access default value
function b() { return env.b; } const bReading = b();
access static value
function c() { return config.c; } const cReading = c();
