const consoleDummy = { warn: () => {}, log: () => {}, error: () => {}, info: () => {} };
const { warn, log, error, info } = window.console || consoleDummy;

const $flags = {
  warn: true,
  log: true,
  error: true,
  info: true,
};

window.console.warn  = (...args) => { $flags.warn  && warn(...args) };
window.console.log   = (...args) => { $flags.log   && log(...args) };
window.console.error = (...args) => { $flags.error && error(...args) };
window.console.info  = (...args) => { $flags.info  && info(...args) };

window.$setConsoleFilter = (flag, value) => { $flags[flag] = value };
window.$toggleConsoleFilter = (flag) => window.$setConsoleFilter(flag, !$flags[flag]);
