javascript array of objects

JavaScript
//create array
var things = ["banana", "car", "computer"];
//access array(starts at 0)
things[0]
//iterate through an array
for (var i = 0; i < things.length; i++) {
  things[i]
}The JavaScript filter() method has several components to its syntax.

newArray = initialArr.filter(callback);
newArray: you name the array that will consist of the filtered elements.
initialArr: the name of the original array.
callback: the method applied to the initialArr.
The callback can have three arguments as well:

element: the current element of the array.
index: the index number of the currently handled value.
array: the original array.
Therefore, the full syntax of the JavaScript array filter function would look like this:

newArray = initialArr.filter(callback(element, index, array));[element0, element1, ..., elementN]

new Array(element0, element1[, ...[, elementN]])
new Array(arrayLength)var widgetTemplats = [
    {
        name: 'compass',
        LocX: 35,
        LocY: 312
    },
    {
        name: 'another',
        LocX: 52,
        LocY: 32
    }
]var cars = ["Saab", "Volvo", "BMW"];
 // Simple array of objects

var arr = [
  {
    first_name: 'Terry',
    last_name: 'Tinseltits',
    age: '47'
  },
  {
  	first_name: 'Frederick',
    last_name: 'Foreskin',
    age: '-1'
  },
  {
  	first_name: 'Wendy',
    last_name: 'Wheelbarrow',
    age: '84'
  }
];

// Of course not, all the objects have to be the of the
// same type as in the above example
