How can I remove an element from a list, with lodash?

As lyyons pointed out in the comments, more idiomatic and lodashy way to do this would be to use _.remove, like this

_.remove(obj.subTopics, {    subTopicId: stToDelete});

Apart from that, you can pass a predicate function whose result will be used to determine if the current element has to be removed or not.

_.remove(obj.subTopics, function(currentObject) {    return currentObject.subTopicId === stToDelete;});

Alternatively, you can create a new array by filtering the old one with _.filter and assign it to the same object, like this

obj.subTopics = _.filter(obj.subTopics, function(currentObject) {    return currentObject.subTopicId !== stToDelete;});

obj.subTopics = _.filter(obj.subTopics, {subTopicId: stToKeep});

javascript arrays object lodash

Just use vanilla JS. You can use splice to remove the element:

obj.subTopics.splice(1, 1);

javascript arrays object lodash

you can do it with _pull.

_.pull(obj["subTopics"] , {"subTopicId":2, "number":32});
