javascript code to calculate the quantity of arrays within a nested array

I am currently working on creating an if statement that will help me determine if the nested array contains only one sub-array. I specifically need to count the objects inside the removeByNames array. I am using angularJS and linq.js, trying to find out which one is more efficient for this task.

[{
    "style":"smooth",
    "color":"blue",
    "data":[[600,40000]],
    "name":"Subject Property",
    "removeByNames":[["Product1"]],
    "$$hashKey":"object:30"
}]

Answer №1

To access the data in an array, you can use a combination of array access and dot notation.

var objectArray = [{"style":"smooth","color":"blue","data":[[600,40000]],"name":"Subject Property","removeByNames":[["Product1"]],"$$hashKey":"object:30"}];

objectArray[0].removeByNames.length;
/* or */
objectArray[0]['removeByNames'].length;
