expect(newDateHelper.postedOn(from)).to.equal('25 Feb 2015');

All tests are currently passing, but because postedOn
compares to the current year I will need to update those tests each year. How can I fix this?
您如何看待模板字面量以及如何获取当前年份?
const from = `Wed Feb 25 ${new Date().getFullYear()} 00:38:24 GMT+0200 (EET)`;
