Creating array of objects dynamically based on length

I have the length of my previous object and i need to create a new array of objects based on the length with new key's.

Length = 3;

var newArray = [];
for(var i =0; i <3; i++){
    var Object = {};
    Object['newKey'] = 1;
    newArray.push(Object);
}

This would eventually create newArray of Objects whose length is 3 containing something like this.. newArray[0],[1],[2].

Am i doing this correctly, please do suggest me if anything wrong or a better way to do this.

You could make it slightly more dynamic by referencing the variable for length.

Example updated per comments:

var length = 3,
    newArray = [];

for ( var i=0; i<length; i++ ) {
    var tempObj = {};
    tempObj['newKey'] = 'SomeValue';
    newArray.push(tempObj);
}

I didn't really do more than clean up what you have.

Here's what you wrote (I think), just shortened a bit (and fixed the capitalization of variable names)

var length = 3;
var newArray = [];
for( var i = 0 ; i < length ; i++ ) {
    newArray.push({newKey: 1});
}

but to be honest it's unclear to me exactly what you're trying to accomplish
