How do you get the first element from an array like this:
var ary = ['first', 'second', 'third', 'fourth', 'fifth'];
I tried this:
alert($(ary).first());
But it would return [object Object]
. So I need to get the first element from the array which should be the element 'first'
.
The memory address of the first element of an array is called first address, foundation address, or base address. Because the mathematical concept of a matrix can be represented as a two-dimensional grid, two-dimensional arrays are also sometimes called matrices.
You can use find() to get the first element. var firstItem = yourArray.
get() is an inbuilt method in Java and is used to return the element at a given index from the specified Array. Parameters : This method accepts two mandatory parameters: array: The object array whose index is to be returned.
like this
alert(ary[0])
Why are you jQuery-ifying a vanilla JavaScript array? Use standard JavaScript!
var ary = ['first', 'second', 'third', 'fourth', 'fifth']; alert(ary[0]);
