js数组对象转换成json

let array = [{'name': 'a', 'value': '1'}, 
			 {'name': 'b', 'value': '2'},
			 {'name': 'c', 'value': '3'}];
var json = {};
for(var index in array ){
	var item = array[index];
	var newkey,newvalue;
	for(var key in item){
		if(key == 'name'){
			newkey = item[key]
		}
		if(key == 'value'){
			newvalue = item[key]
		}
	}
	json [newkey] = newvalue;
}

结果： json = {a: 1,b: 2, c: 3};
