I'd go with the following:

const disableOutputWrapper = process.env.YARN_WRAPOUTPUT === '0' || process.env.YARN_WRAPOUTPUT === 'false';
const shouldWrapOutput = !disableOutputWrapper && !commander.json && command.hasWrapper(commander, commander.args);

if (shouldWrapOutput) {

const outputWrapper = !commander.json && outputWrapperEnv && command.hasWrapper(commander, commander.args);

if (outputWrapper) {
reporter.header(commandName, {name: 'yarn', version});
