size and length in javascript

Question

what is the difference between array.size() and array.length() , and show me the example thanks

Answer 1

I think that you think about about:
array.size()
and
array.length

array.length is property that returns number of elements in array.

----------
Example:
----------
var array =["one","two","three"];
var array2 = [1,2,3];
var array3 = [[1,1],[2,2],[3,3]];

console.log(array.length); //3
console.log(array2.length); //3
console.log(array3.length); //3
----------

array.size() is a function for example in jquery library, when you dont have this library on you project output returns

----------
Example
----------
var array =["one","two","three"];
var array2 = [1,2,3];
var array3 = [[1,1],[2,2],[3,3]];

console.log(array.size());
console.log(array2.size());
console.log(array3.size());

// TypeError: array.size() in not a function
