## Open Source SDK Generators { #open-source-sdk-generators }

A versatile option is the [OpenAPI Generator](https://openapi-generator.tech/), which supports **many programming languages** and can generate SDKs from your OpenAPI specification.

For **TypeScript clients**, [Hey API](https://heyapi.dev/) is a purpose-built solution, providing an optimized experience for the TypeScript ecosystem.

    // We extend the recursive expression for the one-variable case at Art of Computer Programming
    // vol. 2, Knuth, 4.2.2, (16) to the two-variable case. We have two value series x_i and y_i.
    // We define the arithmetic means X_n = 1/n \sum_{i=1}^n x_i, and Y_n = 1/n \sum_{i=1}^n y_i.

That's why it makes a lot of sense to use asynchronous ⏸🔀⏯ code for web APIs.

This kind of asynchronicity is what made NodeJS popular (even though NodeJS is not parallel) and that's the strength of Go as a programming language.

And that's the same level of performance you get with **FastAPI**.

<h2 id="conclusion">Conclusion</h2>

<p>
Go programmers writing data-race-free programs can rely on
sequentially consistent execution of those programs,
just as in essentially all other modern programming languages.

<p>
When it comes to programs with races,
both programmers and compilers should remember the advice:
don't be clever.

  A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.

  The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of

Instructions, registers, and assembler directives are always in UPPER CASE to remind you
that assembly programming is a fraught endeavor.
(Exception: the <code>g</code> register renaming on ARM.)

In Go object files and binaries, the full name of a symbol is the
package path followed by a period and the symbol name:
