JavaScript How to make iterator usable inside async callback function Correct Writing
Example
var pipeline = {};
// (...) adding things in pipeline
var processOneFile = function(key) {
fs.stat(pipeline[key].path, function(err, stats) {
if (err) {
// clear that one
delete pipeline[key];
return;
}
// (...)
pipeline[key].count++;
});
};
// verify it is not growing
for(var key in pipeline) {
processOneFileInPipeline(key);
}
By creating a new function, we are scoping key inside a function so all callback have their own key instance.
