在JavaScript中有没有更简单的方法或者不同的方法来处理这个标志验证？

let flag = true;

if (flag) {
  console.log("Flag is true");
} else {
  console.log("Flag is false");
}

const Flags = {
  ENABLED: 'enabled',
  DISABLED: 'disabled'
};

let flag = Flags.ENABLED;

if (flag === Flags.ENABLED) {
  console.log("Flag is enabled");
} else if (flag === Flags.DISABLED) {
  console.log("Flag is disabled");
}

const FLAG_ENABLED = true;
const FLAG_DISABLED = false;

let flag = FLAG_ENABLED;

if (flag === FLAG_ENABLED) {
  console.log("Flag is enabled");
} else if (flag === FLAG_DISABLED) {
  console.log("Flag is disabled");
}

class Flag {
  constructor(enabled) {
    this.enabled = enabled;
  }

  isEnabled() {
    return this.enabled;
  }

  setEnabled(enabled) {
    this.enabled = enabled;
  }
}

let flag = new Flag(true);

if (flag.isEnabled()) {
  console.log("Flag is enabled");
} else {
  console.log("Flag is disabled");
}

const _ = require('lodash');

let flag = true;

if (_.isTrue(flag)) {
  console.log("Flag is true");
} else {
  console.log("Flag is false");
}
