like below fixes the issue I have a MYSQL query that returns data using PDO::FETCHASSOC. The array is then encoded using json.encode. , Dont do .push().
Instead, do:
code :
var percents = <?php get_percent('accantonamenti irreperibili', $pdo)?>;
console.log(percents.perc_worst);
console.log(percents.perc_best);

To fix the issue you can do I have a request.json in mootools to get some data from a php function returning the following: , You access the json data as a normal javascript object.
code :
onSuccess: function(jsonData){
    var container = document.id('container');
    var items = jsonData.listItems;
    Array.each(items, function(row){
        new Element('div').adopt(
            new Element('h1', {text:row.sessionName}),
            new Element('h2.count', {text:row.sessionCount})
        ).inject(container);
    });
}

wish helps you Assuming you have an object, not JSON, or parse the JSON into an object, you can use Array.reduce
code :
var max = obj.results.reduce(function(a,b) {
    return a.data5 > b.data5 ? a : b;
});
var max = obj.results.reduce( (a, b) => a.data5 > b.data5 ? a : b );

Hope that helps Try like this.
JSON is string.Directly javascript's length property will not works.You have convert it to object first using JSON.parse().
code :
json ='{"results":[{"eventName":"Rey","name":"Tar","dateOfShow":"2017-01-27T22:00:00","userGroupName":"Bit","eventHallName":"Grnn","imageSource":"test2.jpg"},{"eventName":"Gor","name":"Skum","dateOfShow":"2017-01-30T20:00:00","userGroupName":"Gaf","eventHallName":"Gai","imageSource":"test1.jpg"}]}';
res = JSON.parse(json)
alert(res.results.length);

it fixes the issue I'm net to RN, and I wanted to try out mapping data from a data array in .json file inside a for loop if possible or any looping but it should map from the data array. , I think maybe you can try like this :
code :
renderItem() { 
    const elements = [];
    const array = users.map(function(x,i){
        elements.push(x.name.first)
        return (
            <Text key={i}>{x.name.first}</Text>
        );
    })
    console.log(elements);
    return array;
}
render() {
    return (
        <View>
            {this.renderItem()}
        </View>
    );
}
