The comments will provide a course to hide the code so that there is less confusion. Th e comments will need to be removed though if the substance abuser updates their browser to a newer version as they will need to read what is in the comments preferably than what isnt. This is an effective way of providing support for quaternary versions of browsers without having to rewrite the code repeatedly as you can Just trade the comments to change the version of the script to what the browser supports.Older browsers are more likely to render pa up messages whereas the newer versions will use selective information validation to stay information. The older version forced the user to make a simple choice (usually selecting an option victimization boxes or radio buttons), this was an effective method to make sure that the nformation that was input was valid, it may not be true as the user may halt selected the defective box by mistake, but it did touch on the chance of a mistake organism made as they didnt have to bout anything.When compared to nowadays where we use va lidation rules to check that the data that the user has input is this gives the put-on that the user has been given more regard over what is input however, they still have to match the criteria so that the data that they use is valid. Newer browsers lso have navigation features like the anchor, which is apply to direct the user to a specific part of the page when clicked.These can be good when the user is reading a long document (i. e. a manual) and they privation to skip to a certain part, using an anchor they could Jump to the page that they are looking for without having to skip past it. Google optimises their code so that it is compressed so that it can be uploaded faster so the user will be able to view the webpage faster. Web Browser By themavryan
