I have a loop thats looping through some data and getting some fiel values from it.
for (var i = 0; i < mainData[0].main.length; i++) {
var obj = mainData[0].main[i];
var cars = obj.cars;
console.log(cars);
}
This is returning
26
65
34
12
etc
What I need is to put this in a format so it looks like this:
[26, 65, 34, 12]
How can I do this?
You could just map the result and get an array.
cars = mainData[0].main.map(a => a.cars);
ES5
cars = mainData[0].main.map(function (a) { return a.cars; });
You can try this
var result=[];
for (var i = 0; i < mainData[0].main.length; i++) {
var cars = obj.sub.cars;
result.push(cars);
}
console.log(result);
If you are trying to print just the array, you can use console.log(array)instead of looping over everything in the array.
for example, assume this is the array.
var primes = [2,3,5,7];
console.log(primes);
will output [2,3,5,7]
obj.sub.carsfrom?obj.sub.carschanging with each iteration?carscontains a single value or an array?
