TypeScript 2.7 recently shipped with many new features, so many that some developers sparked a debate about the language's "bloat."
Bloated or not, the programming language's functionality provides several time-saving features for VS Code 1.20 users. A new Quick Fix lets developers select a flagged error in source code -- such as a method that has been declared but not yet implemented -- and fix it via options provided in the editor's lightbulb icon. If the same error exists in multiple locations in a file, devs can use a new "Fix all in file" option to address them in one action.
VS Code also now provides more intelligence when suggesting properties, such as when you type a dot after a variable name to bring up a list of possible properties that you can choose from. Now, those available properties will be presented even if they contain whitespaces or other non-identifier characters. What's more, choosing one of the suggestions automatically converts it to bracket accessor notation.
"As an example, let's say you want to use a unicorn emoji as one key in your JSON object and another key that contains a space within it," said Microsoft Cloud Developer Advocate Brian Clark in a video. "VS Code can intelligently suggest those keys and provide bracketed completions when you want to use them."
Another new TypeScript feature provides automatic member property suggestions, so when you start typing a property name and select the appropriate property from a list of possible matching properties that pops up, the required "this." prefix will automatically be prepended to the property.
- Suggestions for optional TypeScript properties are now suffixed with a "?".
Regarding the latter item, the VS Code team explained: "TypeScript plugins were first introduced in TypeScript 2.3, but they previously required installing plugins into your workspace with npm and then configuring a jsconfig.json or tsconfig.json file to load them. VS Code 1.20 simplifies this by allowing extensions to contribute a set of global TypeScript plugins that are automatically activated without any configuration. All you need to do is install the extension."
The team also detailed a slew of other highlights for the release concerning the workbench, editor, languages, debugging and more, boiling them down into this capsule summation:
