I have a global variable 'results' which is a string that will be used by two functions that run a process and append their output to the 'results' variable. However, the functions take time to process and return the result. Following is the current format of the code.
var results = 'Results: ';
router.get('/',function(req,res){
app1.processImage(path, function(err, output){
console.log('app1 processing completed');
results = results+'app1 result:' + output;
});
app2.processImage(path, function(err, output){
console.log('app2 processing completed');
results = results+'app2 result:' + output;
});
console.log('Both processes are completed');
console.log(results);// none of the results printed.
});
When I try to print the results, it doesn't have the outputs yet. the program produces output like this
current output:
Both the processes are completed
Results:
app2 processing completed
app1 processing completed
Expected output:
app1 process completed
app2 process completed
Both the processes are completed
Results: app1 result : true , app2 result:true
Notice that the current output results are empty as the functions are not processed yet. How can I get the results properly stored in the variable?
