Expanding on the previous response, if you are currently utilizing libraries like underscore
or lodash
, you have the option to employ their _.any()/_.some()
function:
var exists = _.any(this.conversations, function(conversation) {
return _.isEqual(conversation, response.data.conversation);
})
Another approach is utilizing Array.prototype.some
for achieving a similar outcome:
var exists = this.conversations.some(function(conversation) {
return _.isEqual(conversation, response.data.conversation);
})
The advantage of these methods over your own solution lies in their ability to return upon finding a match swiftly (instead of processing the entire array), though it is feasible to enhance your code to terminate the loop prematurely.
In addition, although using _.isEqual()
is effective, you may explore comparing specific properties directly (if your objects are sufficiently uncomplicated or, better yet, possess a unique key for identifying conversations) to ascertain equivalence between two objects:
var exists = this.conversations.some(function(conversation) {
return conversation.id === response.data.conversation.id;
})
