This issue has been raised a few times before, but my situation is slightly different. I am new to JavaScript and have created this basic program to demonstrate the problem.
var iterations = 0;
function someFunc(x, y, z) {
for (var i=0; i<4; i++) {
x[i] = x[i] * 2;
y[i] = y[i] * 2;
z[i] = z[i] * 2;
}
iterations++;
if (iterations >= 10)
return {done:true, x, y, z};
else
return {done:false, x, y, z};
}
function main() {
var x = [0, 0, 0, 0];
var y = [1, 1, 1, 1];
var z = [2, 2, 2, 2];
done = false;
while (!done) {
let {done, x, y, z} = someFunc(x, y, z);
console.log(x, y, z);
// Do some other stuff with x,y,z here,
// like calling anotherFunc(x, y, z)
}
}
main();
An error occurs on the line where someFunc is called. The error message reads "Exception Occurred: Reference error: x is not defined".
My goal is to update arrays within a loop by calling a function repeatedly. I need to retrieve these arrays from the function 'someFunc' so that I can pass them to another function for additional processing.
Afterward, I must return them to the initial function again in a cyclical manner until completion.
In Python, calls such as
a, b, c = someFunc(a, b, c)
work smoothly.
However, I am uncertain about how to proceed in JavaScript. Any guidance would be greatly appreciated. Please let me know if further clarification is needed.
