Suppose I have the following data:
let testData = {
'numGroup1': [[(1, 2, 3, 4, 5), (5, 6, 7, 8, 9)]],
'numGroup2': [[(10, 11, 12, 13, 14), (15, 16, 17, 18, 19)]]
};
What is the best approach to iterate through this data using JavaScript?

let sample_data = {
'groupA': [[2, 4, 6, 8, 10], [12, 14, 16, 18, 20]],
'groupB': [[22, 24, 26, 28, 30], [32, 34, 36, 38, 40]],
};
for(let key in sample_data){
group = sample_data[key];
for(let num in group){
console.log(group[num]);
}
}
@Ian made a valid point... utilizing () will only return the last number of each group. It is advisable to use a multi-dimensional array instead.
'groupA': [[2, 4, 6, 8, 10], [12, 14, 16, 18, 20]],
'groupB': [[22, 24, 26, 28, 30], [32, 34, 36, 38, 40]],
Utilize the power of underscorejs for easy iteration
var example_data = {
'groupA': [[1, 2, 3, 4, 5], [5, 6, 7, 8, 9]],
'groupB': [[10, 11, 12, 13, 14], [15, 16, 17, 18, 19]],
};
_.chain(example_data).map(function(val, key) {
return val;
}).flatten().each(alert);
