Method: 1. Use the length attribute to get the length of the array, the syntax is "array element.length"; 2. Use the for loop to reverse the array, the syntax is "for(var i=array length-1; i>=0;i--){document.write(nay[i] '

In jquery, through the for loop, the array elements can be reversed and output by using the key name reverse order method.
Create a new html file, named test.html, to explain how jquery reverses the output of the array. Within the js tag, create an array nay for testing. Get the length of the array through the length property.
The length property contains the number of elements in the jQuery object.
Use the for statement to traverse the elements of the array and specify that the output starts from the maximum value of the key name (len-1). Use the write method to output array elements.
Open the test.html file in the browser to view the results.
