If I receive an array of data
var information = {"response":"OK","details":[["Marco","123"],["John","44245"],["Wayne","645464"]]}
How do I loop through them and log the corresponding values to the console?
Marco 123
John 44245, ..
Marco - 123
John - 44245, ...
for (var i = 0; i < info.length; i++) {
}
data.data.forEach(element => {
console.log(`${element[0]} - ${element[1]}`);
});
for (let j = 0; j < dataArray.items.length; j++) {
console.log(dataArray.items[j]);
}
This seems straightforward, but is there another aspect of the problem I'm overlooking?
Update:
It turns out it was deceivingly simple...
To confirm the accuracy of my answer, to extract only the values from the data within dataArray, the correct approach is:
const dataArray = {"result":"Success","items":[["Sarah","333"],["Mike","789"],"Eva","456"]]};
for (let j = 0; j < dataArray.items.length; j++) {
console.log(dataArray.items[j][1]);
}
However, @user987654 offered a more efficient solution.
When working with a data object, the key to accessing the actual data is through data.data. This will give you an array of values that you can then iterate through to extract each individual value.
var data = {"status":"Success",
"data":[["Alice","456"],["Bob","7890"],["Eve","12345"]]
}
var newData = data.data; //the data key holds an array
newData.forEach(function(item){
item.forEach(function(innerItem){
console.log(innerItem)
})
})
