Javascript (or Node.js) is not returning objects as expected.
The following code logs an empty array.
const _sodium = require('libsodium-wrappers');
const sodium = (async () => {
await _sodium.ready;
return _sodium;
})();
console.log(Object.getOwnPropertyNames(sodium));
On the other hand, the following code works as expected.
const _sodium = require('libsodium-wrappers');
(async () => {
await _sodium.ready;
const sodium = _sodium;
console.log(Object.getOwnPropertyNames(sodium));
})();
In the first code snippet, it seems like the sodium object is tied to its lexical environment, which would explain why an empty array is printed. I would be interested in what's going on here (including an explanation of what's going on under the hood). Thanks.
It's not about lexical context.
You just not awaiting for ready in the first example.
First example simplified:
(async() => {
console.log('start')
await new Promise(r => setTimeout(r, 3000))
console.log('finish')
})()Second example simplified:
console.log('start');
(async() => {
await new Promise(r => setTimeout(r, 3000))
})();
console.log('finish')
