/Program to determine whether the string is palindrome or notfunction checkPalindrome(str) "; // input const string = prompt('Enter a string: ') //use the functionconst value = checkPalindrome(string) andconsole.log(value);

After that, we'll check out the appearance after it's been remodeled:

function checkPalindrome(n)const t=string.length;for(let n=0;n

The second code block is considerably smaller and smaller. It loads and renders faster, which cuts down on the amount of time required to load webpages and speeds up the loading of content.

The 529 bytes are reduced to 324 bytes. In addition, we've added 205 bytes of space as well as reducing the loading time for the site by more than 40.

It's like being a book having 529 pages which is cut down to 324 pages. Naturally, a person may have difficulty with this however computers can run through it with no issues.

What can you do to reduce JavaScript Code?

JavaScript is supported by an application called UglifyJS which lets users uglify code in a manner which is automated. This enhances the efficiency of the code and decreases the ability to read it, making it more difficult for thieves to steal.

Minification is the process that minimizes the amount of whitespace and comments. Completely removing a code changes it into code that isn't readable by changing the names of variables, function names and so on. The code is compressed and converted into binary format to decrease file size. files.
