TypeScript as fast as Rust: TypeScript++

TL;DR: This is a proposal to create a language that sits somewhere between Typescript and Rust, and which you can incrementally adopt if you already use Typescript.

Typescript and Rust can feel pretty similar:

// Typescript
type Vec2 = { x: number, y: number };

function avgLen(vecs: Vec2[]): number {
    let total = 0;
    for (const vec of vecs) {
        total += Math.sqrt(vec.x*vec.x + vec.y*vec.y);
    }
    return total / vecs.length;
}
// Rust
struct Vec2 { x: f64, y: f64 }

fn avg_len(vecs: &[Vec2]) -> f64 {
    let mut total = 0.0;
    for vec in vecs {
        total += (vec.x*vec.x + vec.y*vec.y).sqrt();
    }
    return total / vecs.len() as f64;
}

In some ways, Rust feels like a more restrictive but faster version of Typescript. But Typescript/Javascript can be very fast too; owing to years of hard work by browser vendors. In this article we’ll look at the performance characteristics of each in more detail, and see if we can have the best of both worlds.
