It's also valid rust syntax.

But if it were rust, this meme would not make sense, since you would just type let a and type inference would do its thing. Which is much more ergonomic.

    let a = String::from(“Hello, world!”).into()

    I’ll see myself out.

    At least be fair and cut out the .into()

    And bow to the compiler’s whims? I think not!

    This shouldn’t compile, because .into needs the type from the left side and let needs the type from the right side.

    Type inference is a pretty big thing in TypeScript as well though. In fact it's probably the biggest thing about it, IMO.

    I don't know typescript. But if that's the case, this meme doesn't make much sense.

    Who writes the types of variables in a language with type inference unless forced by the compiler?

    Maybe it's a language without type interference?

    Either way, it sometimes makes sense in TypeScript to help the type system out a little bit.

    let array: string[] = [];

    In this situation, the type system can't infer that the empty array should be a string array, because there are no items to go by.
