Display array elements without numerical indexes

Consider the code snippet below:

    for(i=0; i<3; i++){
         a = {};
         a['name' + i] = i;
        data.push(a);
}

This code will generate the following array:

{
1:{name0:0},
2:{name1:1},
3:{name2:2}
}

How can I modify the code so that it produces the array in this format:

{
name0:0,
name1:1,
name2:2
}

The reason behind this adjustment is to be able to conveniently access array elements by name, such as data[name1], rather than having to search through the entire array.

Answer №1

It is recommended to use data directly as an object instead of storing it as an array (which would result in an array of objects)

 for(i=0; i<3; i++){
    data['name' + i] = i;
}

Remember, data should be initialized as an object (like var data = {})
