Unminified JavaScript: A Quick Peek into the Original Code

Let us delve deeper into the process by looking at an unminified JavaScript code:

function myFunction(myNumber){

     var myArray = new Array(myNumber);

     var myObject = new Object();

     var myArray2 = new Array();

     for(var myCounter = 0 ; myCounter < myArray.length ; myCounter++){

         myArray2.push(myCounter);

         var myString = myCounter.toString()

         myObject[ myString ] = ( myCounter + 1 ).toString();

     }

    var myContainer = new Array();

    myContainer[0] = myArray2;

    myContainer[1] = myObject;

    return myContainer;

}

As you can see, the code is neat and comprehensible. Now, let’s feed it into a minifier tool.

Post-minification: The Result

Once we minify the code, it transforms into a compact and efficient version:

function myFunction(r){

 for(var n=new Array(r),t=new Object,e=new Array,a=0;a<n.length;a++){

  e.push(a);

  var o=a.toString();

  t[o]=(a+1).toString()

 }

 var i=new Array;

 return i[0]=e,i[1]=t,i

}

Despite the significant variance in appearance, both the original code and its minified counterpart perform the same functionality. The minified version is more cryptic, making it challenging to discern its purpose at first glance.

Test and Compare Performance

Testing both code versions will reveal a noticeable speed difference, affirming the efficiency of minification. Being harder to comprehend, the minified version also offers an element of security, protecting your program from potential plagiarism.
