Here is the data I have:
data: function() {
return {
conversations:
[
]
}
}
I am retrieving my data from the response object using response.data.conversation
Is there a method to verify if this.conversations already includes response.data.conversation?
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;
})
The solution has been discovered:
Employed underscore.js.
Iterate through all elements in the array and compare them using the _.isEqual(a,b)
function
var counter=0;
for(var index=0; index<this.conversations.length; index++ ) {
if(_.isEqual(this.conversations[index], response.data.conversation)) {
counter++;
}
}
Next, evaluate the value of the counter variable:
if (counter == 0) {
//Add element to the array
this.conversations.push(response.data.conversation);
} else {
console.warn('exists');
}
