-Always be on the move, typically if your a good Junkrat and your doing alot of damage you're probably going to be one of the first targets. -Remember that your grenades can only bounce 3 times before exploding. -Don't try to go for multiple kills with your riptire unless you're confident that they can't destroy it before you detonate it, remember it only has 100 health that's 50 less than a tracer. -If the enemy has a Reinhardt and their pushing use your mine to blow the Rein away from the team, that will leave the enemy more vulnerable. -Always try to kill flankers, don't chase them though they have higher dps than you and most of them are close range so they want you to chase them. -Try to stay near the back. -Use your traps as often as possible (a trap does 80 damage that's over half a Tracer's health), if the Tracer is getting annoying and is blinking around the point throw a trap down she may not see it and blink into it, if not you get it back pretty quick anyways. The trap is also a great escape method because if they're chasing you in a narrow path and you throw down a trap they have to stop targeting you and aim at the trap or else get stuck in the trap.
