I found a more effective method to accomplish the task in my JavaScript project by utilizing the Lodash library. The approach involves extracting properties, splitting arrays, and obtaining unique values.
var taskobj = [
{'taskno':'a', 'team':'1,2'},
{'taskno':'b', 'team':'3,4'},
{'taskno':'c', 'team':'2,4'},
];
//Iterating through the object to convert strings into arrays
_.forEach(taskobj, function(value, key) {
taskobj[key].team = _.split(taskobj[key].team,',');
});
// Using _.map to extract teams and return an array
// Utilizing _.flatten to flatten the array
// Applying _.uniq to obtain unique values from the flattened array
return _.uniq(_.flatten(_.map(taskobj,'team')));
// Output - [1,2,3,4]
Do you think this is the most efficient way to achieve the desired outcome?
