When writing code, I frequently encounter situations that resemble the following:
function example(parameter: string) {
const tuple = [
"newParameterValue",
"newVariableValue"
]
let newVar;
[parameter, newVar] = tuple;
}
(Typically, this also involves async/await and Promise.all, where multiple async operations are run in parallel. However, these specifics are not pertinent to the current query). The key issue is that I need to destructure a tuple, assigning one value to an existing variable while creating a new variable for another value.
The approach works, but I find it cumbersome as I have to declare newVar using let rather than
const</code, and separate its declaration from assignment. This method feels inefficient and messy. Ideally, I would prefer something like:</p>
<pre><code>function example(parameter: string) {
const tuple = [
"newParameterValue",
"newVariableValue"
]
[parameter, const newVar] = tuple;
}
Unfortunately, this syntax does not compile.
What is the correct and standard way to write this code?
