Question

How can I change the key name in an array of objects?

var arrayObj = [{key1:'value1', key2:'value2'},{key1:'value1', key2:'value2'}];

How can I change each key1 to stroke so that I get:

var arrayObj = [{stroke:'value1', key2:'value2'},{stroke:'value1', key2:'value2'}];

Answer 1

var i;
for(i = 0; i < arrayObj.length; i++){
    arrayObj[i].stroke = arrayObj[i]['key1'];
    delete arrayObj[i].key1;
}
