Hi.
I have never written a proposal before, but I would love if it was possible to
do the following in JavaScript:
```js
// This code exposes a function that when called bound to an `object` inserts a
method in that `object`.
// The following are 3 ways to do this, the last one being my proposal. Note
that I am using CommonJS
// require style to include modules, but that is simply to illustrate how I
came up with thi. Using `export default function…`
// does not really address my use case, but just for completeness I have
included an example using the new `import`
// `export` system as well.
// Disclaimer: This is a simple plugin-like system example, but notice I am not
checking whether the
// method already exist in `object`. You can ignore this.
// Idiomatic JavaScript
module.exports = function () {
let method = require("./lib/method")
this.method = function (…args) {
return args.map((arg) => method(arg))
}
}
// Clumsy, but without using `let` variables
module.exports = function () {
this.method = function (…args) {
return (function (method) {
return args.map((arg) => method(path))
}(
require(“./lib/method")
))
}
}
// My proposal is to allow blocks to receive arguments (similar to the
non-standard let blocks) and
// whatever you return inside the block is the return value of the enclosing
function. Also, there
// should be no need to write `return` as it will always return the result of
the last expression.
module.exports = function () {
this.method = function (…args) {
(method) { args.map((arg) => method(arg)) }(require("./lib/method")
}
}
// Just for completeness, but not really related to what I am proposing
(although it
does solve this particular case very neatly) using import & exports
import method from "./method"
exports default function () {
this.method = function (…args) {
return args.map((arg) => method(arg))
}
}
```
If you think this is a good or bad idea, please let me know your comments and
observations.
Regards
J
