Does Dual Wielder allow you to add your ability mod to the off-hand weapon?

@JeremyECrawford Does Dual Wielder allow you to add your ability mod to the off-hand weapon, like with Two Weapon Fighter?

The Dual Wielder feat doesn't include the benefit of the Two-Weapon Fighting feature. It would say so if it did. #DnD https://t.co/1fpgCaz87O
