Something about a semicolon in JS

I made a script to set keyboard and mouse controls and 2 lines say I need a semicolon at the end. There already is one for each line. I think it has to do with using an “Int” command.

int UnityEngine.ParticleSystem.CollisionEvent.velocity=20;

int UnityEngine.Component.particleEmitter.particleSystem.emissionRate(15);

If I’m not supposed to have so many children to the parent or the “int” the website and compiler told me to, or so I thought…
These explanations on the site and the “expecting “random thing you already have”” tips just confuse me. The sad thing is I know a buttload of computer languages in concept, I just can’t code for crap!

There is no “int command” in JS. That’s C#.
