+
+The `return` keyword is mostly used for returning early.

+
+Integers come in many sizes with the smallest being 8-bit and the largest 128-bit. However there is also `usize or isize` which specifies that the size is dependent on the CPU architecture.
+
+In contrast, floating points only have two sizes: f32 and f64. There is no fsize.
