    Some sweet highlights from our 4.0 release! 😍

    Go from a ton of boilerplate signatures to just one.
    Avoid making too many assumptions, and get type-safe code with try/catch.
    You can omit types for class properties, and under noImplicitAny, they'll be inferred from the constructor.
    Declarations marked as @deprecated get a visual indication that you shouldn't use them. Expressions that are built up with chains of '&&' can be converted to use the optional chaining '?.' operator.

    Want a glimpse of the not-so-distant future? You can start using optional chaining and null coalescing in today with the TypeScript nightly extension! Both are on track for standardization and will be supported by 3.7
