How to create an array of objects from an existing array in javascript?

I have an array whose elements are in string format, like this:

somearray = ["abc", "pqr", "xyz"]

I need to create an object from this array whose variable I have declared as var newobject = {}. I tried this:

var newobject = {};
var index = 0;
somearray.forEach(function() {
    newobj = {
        name : somearray[index]
    };
    index++;
});

This does create an object but only consisting of the last string in the array (somearray)

If instead of

newobj = {
    name : somearray[index]
};

I write

newobj[index] = {
    name : somearray[index]
};

the objects are named 0,1,2. I don't want this to happen, nor do I want anything else in its place. Isn't there any way like how we use push method for arrays?

Just use key-value notation:

var newobject = {};
var somearray = ["abc", "pqr", "xyz"] ;
somearray.forEach(function(x,i){
  newobject[i]=x;
})
console.log(newobject);

Simple solution using Array.forEach and Array.push functions:

var somearray = ["abc", "pqr", "xyz"], objects = [];

somearray.forEach((v) => objects.push({name: v}) );    
console.log(JSON.stringify(objects, 0, 4));

Or the same using Array.map function:

var somearray = ["abc", "pqr", "xyz"], objects;  
objects = somearray.map((v) => ({name: v}) );

The output:

[
    {
        "name": "abc"
    },
    {
        "name": "pqr"
    },
    {
        "name": "xyz"
    }
]
