Visual Studio Code

Visual Studio Code is a free code editor available on macOS that gives programmers a visual environment for writing, navigating, and managing code. It suits both newer developers who want guidance as they type and more experienced users who rely on integrated debugging and Git tools.

Editing with IntelliSense, debugging, and Git

At the heart of Visual Studio Code is IntelliSense, which goes well beyond simple word completion. As you write, it proposes completions informed by variable types, function definitions, and imported data, so suggestions stay closely aligned with the structure of your project.

The built in debugger scans your code for likely trouble spots and offers possible solutions. You can work with breakpoints and call stacks directly inside the editor, which helps trace how execution flows through an application. This module is useful across experience levels, from people still learning to track bugs to experts investigating complex issues.

Source control is handled in the editor through its Git integration. You can review diffs and stage files without switching to a separate tool, which keeps version control closer to your coding workflow.

Rounding out the core feature set is the extensions module. Visual Studio Code supports various third party extensions, and they are described as not slowing the editor down. You can enrich the environment for specific tasks while maintaining a responsive editing experience.

Support for learners and experts

Visual Studio Code brings clear benefits for people who are not yet very experienced with coding, including those working in languages such as Java. Context aware IntelliSense and the integrated debugger make it easier to spot and correct mistakes as you go.

For expert programmers, however, the editor does not provide a great deal of help in visualizing code. Advanced visual overviews of large systems are limited. Even so, the debug module remains valuable across almost every style of development, since careful inspection of breakpoints and call stacks is widely useful.

Profiles tailored to specific workflows

In version 1.78, Visual Studio Code introduces built in profile templates for Python, Java, data science work, Node.js, and Angular. These curated profiles let you personalize the editor for a particular workflow, streamlining setup when you focus on one of these stacks.

Modern themes and visual tools

The same release updates the default look of the editor with two new themes, Dark Modern and Light Modern. They replace the older Dark+ and Light+ themes and provide a refreshed visual experience for users who spend long stretches in front of the screen.

Visual Studio Code now includes a standalone color picker that you can open to insert new colors or replace existing ones in your code, which simplifies adjusting color values while editing.

The diff viewer benefits from a new algorithm that generally produces better diffs. The older algorithm remains the default and the newer one may be slower for some documents, but there are plans to make the updated algorithm the standard once its performance has been monitored.

Language and testing enhancements

JavaScript handling in HTML blocks gains extra safety through the js/ts.implicitProjectConfig.strictNullChecks setting. Enabling this activates strict null checking for JavaScript within HTML, which can improve code robustness by catching more null related issues.

Visual Studio Code 1.78 also supports TypeScript 5.1, currently in beta, giving developers the opportunity to explore the latest TypeScript features inside the editor.

Testing tools get finer control with an Individual Test Continuous Run feature. Continuous Run can now be activated for specific tests, giving you more flexibility when you want constant feedback on a particular case instead of an entire test suite.

Better Markdown, notebooks, and media handling

Working with Markdown becomes more convenient in this version. You can drag and drop video files into Markdown documents, and you can drop image files into Markdown cells within notebooks. This streamlines adding rich media to documentation and notebook based workflows.

Inline completion and snippet improvements

The inline completion feature has been revamped. Bug fixes improve reliability, and a new Accept Line command lets you confirm an entire suggested line at once. Accept Word now works across line breaks, giving you more control over how much of a suggestion you bring into your code.

Snippet authors gain a new variable called CURRENT_TIMEZONE_OFFSET. It returns the current time zone offset in the +HHMM or -HHMM format, which can be useful when creating snippets that need to insert time zone aware data.

Source control refinements and Git LFS on the web

Inside the Source Control message box, you now have access to Code Actions and Quick Fixes. That makes it easier to address certain issues or apply suggested changes without leaving the place where you are writing commit messages.

For users of Visual Studio Code in the browser, the web version now supports committing files to Git Large File Storage (LFS) in repositories hosted on GitHub. This broadens what you can manage through the web editor when working with large files that use Git LFS.

Accessibility improvements

Visual Studio Code 1.78 introduces several refinements for screen reader users. With the accessibility.verbosity.diff-editor and accessibility.verbosity.terminal settings, you can exclude certain hints from a feature's aria-label, which cuts down on repetitive spoken information. New audio cues add more feedback about what is happening in the editor, contributing to a more user friendly experience.
