Idk... I had problems in the past with weird bugs where the breakpoints do not match the right line although using sourcemaps and all that so sometimes you end up doing stuff like this.
Or if you want to know how many times something executes without well having to "continue" on each breakpoint or similar.
Sometimes I use various swears. Depends on how long I've had to debug. Also depends on whose work I'm debugging and whether they're in earshot. Usually it's just my own sketchy code though.
