[Bug]: Parser accepts illegal syntax obj.[prop] #13694
Description
💻
- Would you like to work on a fix?
How are you using Babel?
Programmatic API (babel.transform, babel.parse)
Input code
val = obj.[prop];Configuration file name
n/a
Configuration
n/a
Current and expected behavior
obj.[prop] is not legal Javascript (note the . before [). Would expect parser to throw an error.
Instead, it parses it as if it was obj[prop] (i.e. without the .).
