17 Code Assists for Syntax Conversion

It is often annoying to make small syntactical changes by editing text. Often more than one position needs to be edited, and the code is broken during the edit, leading to incorrect errors and auto-completions that get in the way. You can execute the following syntax conversions with code assists:

• Add {…} to if-else and loops

  Convert single statements into blocks.

• Add {…} to arrow function

  Convert arrow function expression body into a block body.

• Add {…} to JSX attribute
