`JL` and other conditional jumps/branches are a common type of instruction [0][1][2]. Depending on the ISA [3][4][5], there can be jumps, branches, and subroutine transfers (or even a subset of those). Some can be based (conditional) on what value is in a primary register (often traditionally called the accumulator), a condition/flag/status register, a memory location, and even well known constants (0, 1, -1). Many ISAs have ways branching to a function/subroutine/procedure that can include adjusting a calling stack or transferring control to an OS kernel. x86 is notable in that you can cause a branch or jump without calling a branch or jump instruction.
