Add a Key Value Pair to an array of objects in javascript?

If I had an array as such:

var myarray = [];



myarray.push({

    Name: 'Adam',

    Age: 33

});



myarray.push({

    Name: 'Emily',

    Age: 32

});

This gives me an array where I can pull out values like myarray[0].Name which would give me Adam.

However, after this array is built, how can I add an address field with a value of somewhere street into the array at position [0], so that my fields in that object at position zero are now Name, Age, and Address with corresponding values?

I was thinking splice() somehow but couldn't find an example using objects, just examples with simple arrays.

You can simply add properties (fields) on the fly.

Try

myarray[0].Address = 123 Some St.;

or

myarray[0][Address] = 123 Some St.;

var myarray = [];



myarray.push({

    Name: 'Adam',

    Age: 33

});



myarray.push({

    Name: 'Emily',

    Age: 32

});



myarray[0][Address] = 123 Some St.;



console.log( JSON.stringify( myarray, null, 2 ) );
