Question about circulation output values-CodePudding

 
For (var I=0; i <6; I++) {
Session. PingHost (the list [I] server, (error, target, sent, RCVD)=& gt; {
If (error) {
The console. The log (` failed `); 
} else {
Const spent=RCVD. GetTime () - sent. GetTime (); 
A (target, spent); 
} 
}) 
Var newArr=[]; 
Function a (IP, data) {
The console. The log (" a: "+ I); 
//var newArr=[]; 
NewArr. Push ({
"IP" : IP, 
"ResT" : data 
}); 
The console. The log (newArr) 
} 

The function () {b 
The console. The log (" b: "+ I); 
} 
(b) 
}

Everyone here are two questions to ask:
1. The above For loop, why a (IP, data) {the console. The log (" a: "+ I)} output value has always been a 6, and b () {the console. The log (" b:" + I); } of the output value is 0 b,1,2,3,4,5??

2. Var newArr=[]; Function a (IP, data) {the console. The log (" a: "+ I); NewArr. Push ({" IP ": IP," ResT ": data}); The console. The console in the log (newArr)}. The log (newArr) of the output value below

I just want to output the data in the red box above, other don't output , could you tell me how to write?
