Grouping

Status: implemented

export default ([80, 443]).length;

A value may be written in parentheses, and it denotes that value: (x) is x, so the parentheses leave nothing behind — no node of their own and no change to which values a module shares — exactly as in JavaScript. A group is a value like any other and takes a property access or a call after its ), and it holds one value or the operands of a comma, (a, b), which is an operator of its own (comma) and the one that detaches a receiver.

Once admitted, parentheses leave no node behind, except for the boundary an optional chain makes of them: they end the region a ?. opened. Admission can still depend on source form, as it does for a literal bracket key (property access). They keep a property reference, so (o.m)(a) is the method call o.m(a) is (functions), and they keep sharing, so a const reached through a group is the one value it is reached without one. They launder nothing either: (1).x is the access 1 .x is, (1)(2) the call 1(2) is, and (o.toString)(1) the method call o.toString(1) is, its key judged by the call rule and not the read rule (property access): (a.push)(1) is refused at the key as a prohibited member function, as a.push(1) is, and (o.toString) alone, a read, stays refused.

What a group does change is how far an operator reaches. A group is one operand of whatever operator stands around it, so it overrides precedence and associativity as in JavaScript (operators): (1 + 2) * 3 multiplies the sum, 1 - (2 - 3) and (2 ** 3) ** 2 reverse the default association, (a ? b : c) + 1 adds to the chosen arm, and (1 + 2) ** 2 raises the sum. It bounds how far a prefix reaches too, since - binds looser than a step (unary minus): (-1).x is the access on the negation and -1 .x the negation of the access, as JavaScript reads each. A group is an operand of - as well, and the one way a function reaches the prefix at all: -((...a) => 1) is a value where -(...a) => 1 is a syntax error, there and here.

A parenthesized parameter list, (a, b) => …, is distinguished from a group and from a comma by the arrow following ). Each parameter must be a binding target; (a + b) is a group and (a, b + 1) a comma, while (a + b) => 1 and (a, b + 1) => 1 are refused.

Examples

The compiler demo offers the programs grouping in module.f.js, each with its real output.

The demo on this page runs sample.f.js, this page's example as a function of one number — parentheses that change precedence, and a group a step applies to — with every output fjs compile makes of it: the expression graph (EDAG), the Rust and the WebAssembly that Rust builds to. Its Run button calls the default export with 1 and 2, as JavaScript and as WebAssembly, and shows what each call returned or threw.

export default (...a) => [(a[0] + 2) * 3, a[0] + 2 * 3, ([80, 443]).length];

Reference

Demo

In FunctionalScript

fjs compile accepts this module, and it runs as JavaScript and as WebAssembly alike.

A FunctionalScript module and what fjs compile makes of it: the expression graph it lowers to, the Rust it compiles to on the NaNVM runtime, and the WebAssembly that Rust builds to. Run calls its default export with 1, then 2, first as the JavaScript it already is and then as WebAssembly, and shows what each call returned or threw and how long one call takes, timed over 1000 calls.

FunctionalScript source:

/**
 * The example of [`README.md`](./README.md) (Grouping) as a function of one
 * number, for the page's WASM demo: parentheses that change precedence, and
 * a group a step applies to.
 *
 * @module
 */

/** @type {(...a: readonly number[]) => unknown} */
export default (...a) => [(a[0] + 2) * 3, a[0] + 2 * 3, ([80, 443]).length];

Expression graph (EDAG) that fjs compile lowers it to:

=>lengthbody0[][]012*leftright+3+leftright.objkey[]"length"+leftright.2.objidxrest0*leftright23[]0180443.objidxrest0

The same graph, as fjs compile writes it to a .edag.data.js file:

const $0=["rest"];export default ["{}",[[":","default",["=>",0,[],["[]",[["*",["+",[".",$0,0],2],3],["+",[".",$0,0],["*",2,3]],[".",["[]",[80,443]],"length"]]]]]]];

Rust that fjs compile writes from it, on the NaNVM runtime:

// @generated by `fjs compile`. Do not edit: recompile the source module instead.

use nanvm_lib::vm::unstable::{f64_any, string_any, string_key};
use nanvm_lib::vm::{Any, Array, IStaticFunction, ToAny, ToArray, ToObject};

#[rustfmt::skip]
#[allow(clippy::if_same_then_else)]
pub fn module<A: IStaticFunction>(_runtime: Any<A>) -> Result<Any<A>, Any<A>> {
    Ok([(string_key("default"), A::static_function(|_self, _args| {
        let _b468: Any<A> = _args.rest(0).to_any();
        Ok([(((Any::dot(_b468.clone(), f64_any(0x0000000000000000)).end())? + f64_any(0x4000000000000000))? * f64_any(0x4008000000000000))?, ((Any::dot(_b468.clone(), f64_any(0x0000000000000000)).end())? + (f64_any(0x4000000000000000) * f64_any(0x4008000000000000))?)?, (Any::dot([f64_any(0x4054000000000000), f64_any(0x407bb00000000000)].to_array().to_any(), string_any("length")).end())?].to_array().to_any())
    }, 0, Array::default(), Some("(...$0)=>[($0[0]+2)*3,$0[0]+2*3,[80,443].length]")).to_any())].to_object().to_any())
}
