Unable to organize list of entities based on numerical values

I am working with an array of objects structured like this:

[
    {
        "value": 351.68474,
        "o_p": [
            "$.text"
        ]
    },
    {
        "value": 348.0095,
        "o_p": [
            "$.text"
        ]
    },
    {
        "value": 365.2453,
        "o_p": [
            "$.text"
        ]
    }
]

My goal is to sort this object based on the value property. I attempted the following approach:

const sorted_object = orig_object.sort((a, b) => a.value - b.value);

This sorting technique was suggested when I explored solutions on various platforms.

However, as I implemented this, I encountered an error that has left me puzzled:

ERROR TypeError: Cannot assign to read only property '0' of object '[object Array]'

Could there be an obvious mistake in my implementation? Any insights or suggestions would be greatly appreciated.

Answer №1

When utilizing the Array.prototype.sort method, it is important to note that it modifies the original array. The error you are encountering suggests that you may be working with a read-only array, resulting in the issue when attempting to use the mutating .sort.

If creating a clone of the array is acceptable, one solution is to employ [ ...array ].sort(...) for a "clone-and-sort" approach.
