x86-64 Assembly Jump Instructions Explained: Unconditional JMP with Full Example in Yasm

In this beginner-to-intermediate assembly language tutorial, we dive deep into unconditional jump instructions (JMP) in x86-64 assembly using Yasm syntax.

We cover:
What unconditional jumps really are (basically a "go to" for assembly)
How labels work and how to create them
Why JMP has unlimited range (unlike conditional jumps)
Practical demo showing how to skip code sections using jumps
Comparison between jumping over code vs letting it execute
Quick look at why this matters before learning conditional branching

We also reference the excellent free open-source textbook by Professor Ed Jorgensen (May 2024 version) which is highly recommended for anyone serious about learning x86-64 assembly.

Whether you're preparing for university courses, reverse engineering, operating systems development, or just love low-level programming, this video will give you a clear understanding of how unconditional control flow works in modern x86-64 assembly.

Next video will cover conditional jumps (je, jne, jg, jl, etc.) and their limitations.

Enjoy the video and happy coding at the machine level!
