Length unchanged after using delete
javascript
Solution
The delete operator deletes a property from an object. In your case, property `i`. Properties in an array are actually indexes `0` through `array.length - 1`. Use splice instead:
data.splice(i, 1);
To find out the number of properties in an object, use `Object.keys`:
`Object.keys(data).length` will result in 2
Problem
I have a function which deletes from an object array but when i check it's `.length` its the same.. This is what i have: ``` console.log(data.length); delete(data[i]); console.log(data.length); console.log(data); ``` My outputs end up like this: ``` 3 3 [object Array] ``` I have attatched the image of the object array below, you see only 2 entires but the length is still 3. The initial data im testing with is this: ``` [ {"equip":"0","name":"Test","id":"10"}, {"equip":"0","name":"Test","id":"4"}, {"equip":"0","name":"Test","id":"5"} ] ``` You can see my browser has deleted one from the object array.. so why does it still count 3, and how do I fix that so it counts correctly?
