For example, imagine you have an array like this:,Knowing how to quickly iterate through an array and count objects is deceptively simple. The length() method will tell you the total number of values in the array, but what if you only want to count those values based on certain conditions?,Now that you've filtered out the object with status: '1', just call the length() method on the new array to get the total count of objects with status: '1':

For example, imagine you have an array like this:

const storage = [{
      data: '1',
      status: '0'
   },
   {
      data: '2',
      status: '0'
   },
   {
      data: '3',
      status: '0'
   },
   {
      data: '4',
      status: '0'
   },
   {
      data: '5',
      status: '0'
   },
   {
      data: '6',
      status: '0'
   },
   {
      data: '7',
      status: '1'
   },
];
