Using an array inside a for loop to follow the same structure

Question

Using an array inside a for loop to follow the same structure

I am in need of prompt assistance on how to integrate my array into a for loop.

Currently, my graph accepts the following as nodes:

var classes = [
    {"name":"test.cluster1.item1"},
    {"name":"test.cluster1.item2"},
    {"name":"test.cluster1.item3"}
];

I also have a separate functional array named fileArray, which contains multiple nodes that I wish to include in my graph.

var fileArray = ["a", "b", "c", "etc..."];

I am attempting to replace all instances of "test cluster items" in my data with each element of fileArray. How should I go about achieving this?

The code snippet I currently have doesn't seem logical, and I am at a loss on how to proceed.

for(i = 0; i < fileArray.length; i++) {
    var classes = [
        {"name": fileArray(i)}
    ];
}

Desired outcome:

var classes = [
    {"name":"fileArray[0]"},
    {"name":"fileArray[1]"},
    {"name":"fileArray[2]"},
    {"name":"fileArray[3]"},
    {"name":"fileArray[4]"}
];

Thank you.

Here is an updated version that utilizes the reduce method to create deep copies of each object's property. You can choose to create a new array or modify the existing classes array:

var classes = [
    {"name":"test.cluster1.item1"},
    {"name":"test.cluster1.item2"},
    {"name":"test.cluster1.item3"}
];

var fileArray = ["x", "y", "z", "etc..."];

classes.reduce((acc, curr, i) => {
    acc.push({...curr, name: fileArray[i]});
    return acc;
}, []);

console.log(classes);
