Do I need to know how to code well before using VS Code?

No. VS Code itself is just a well-built, free text editor with an extension system layered on top — you do not need to already know how to program to install it and start writing your first Python script or MATLAB-adjacent analysis file. What VS Code adds over a plain text editor (syntax highlighting, code completion, an integrated terminal, debugging) actually makes learning to code easier, not harder, because mistakes like a missing parenthesis or a wrong variable name are flagged immediately rather than discovered later when the script fails to run.

What is the actual difference between VS Code and Visual Studio, since they sound the same?

They are two entirely different products from Microsoft that happen to share a name. VS Code is the free, lightweight, cross-platform editor this tutorial covers, built around an extension ecosystem. Visual Studio is a separate, much heavier, Windows-only traditional IDE aimed mainly at C#/.NET and native Windows C++ development, with a more powerful built-in debugger and profiler. The companion choosing your engineering IDE guide on this site covers that distinction, and the fuller IDE landscape including Xcode and Android Studio, in more depth.

What extensions should I install first as an engineer new to VS Code?

Start with the language extension matching your actual work: the Python extension for scripting and data analysis, or the C/C++ extension if you are doing embedded or firmware work. From there, the Jupyter extension is worth adding almost immediately if you do any data analysis, since it brings notebook-style interactive execution directly into the editor. A linter (Pylint or Flake8 for Python) and Git integration (built in, but worth learning) round out a genuinely productive baseline setup without installing dozens of extensions you will not use.

Can I really run simulations or scripts without leaving VS Code?

Yes, and this is one of its most practically useful features for engineers. The integrated terminal is a real shell (PowerShell, bash, or whatever your system default is) running inside a panel of the editor, so you can execute a Python script, kick off a MATLAB batch job, or run a command-line simulation tool and watch its output scroll by, all without switching to a separate terminal application or losing your place in the code you're editing.

Is VS Code good for embedded or PLC-adjacent scripting work?

Yes, particularly through the PlatformIO extension, which turns VS Code into a complete embedded development environment supporting Arduino, ESP32, STM32, and many other microcontroller platforms with integrated building, flashing, and a serial monitor. That specific embedded workflow is covered in more depth in the companion choosing your engineering IDE guide on this site, which compares VS Code against Visual Studio, Xcode, and Android Studio for different categories of engineering-adjacent development work.

Does settings sync mean my VS Code setup follows me between computers?

Yes. Signing into VS Code with a Microsoft or GitHub account enables Settings Sync, which carries your installed extensions, keybindings, and editor preferences across every machine you sign into, so a work laptop and a personal computer end up with an identical setup without manually reinstalling and reconfiguring everything twice.

Why VS Code Has Become the Default Editor Across Engineering Disciplines

Visual Studio Code, made by Microsoft, has become the most widely used code editor in the world, and that popularity extends well past professional software developers into engineering-adjacent disciplines that were not its original target audience at all: mechanical engineers writing Python scripts to parse sensor logs, controls engineers scripting MATLAB-adjacent data pipelines, automation engineers writing PLC-adjacent test scripts, and hardware engineers stepping through embedded C code all end up reaching for the same tool. Three things drive this convergence. It is free, with no licensing friction for an individual engineer or a whole engineering department to adopt. It is extensible rather than locked to one language or vendor, so the same editor serves Python, C/C++, embedded firmware work, and general scripting through installed extensions rather than requiring a different dedicated tool for each. And it works identically on Windows, macOS, and Linux, which matters in engineering environments where a Windows desktop, a Linux single-board computer, and a Mac laptop often all need to be touched by the same person in the same week.
