    Thank you @Philippe Dubé-Tremblay for your nice solution (above),

    I will just put here the wrapping function for those who, like me, plan to call this function repeatedly.

    // Accepts a date as parameter or with no parameter will assume the current date.
    const getPreviousMonday = (date = null) => {
      const prevMonday = date && new Date(date.valueOf()) || new Date()
      prevMonday.setDate(prevMonday.getDate() - (prevMonday.getDay() + 6) % 7)
      return prevMonday
    }
