What is Developer mode & how we can enable in magento 1.x

Something you should do in development—but never in production—is to enable Magento's developer mode which, among other things, displays exceptions in your browser. It's useful for debugging your code.

Enable developer mode in any of the following ways:

Developer mode
To do this open the index.php in the root of your Magento installation and remove the comment from the line Mage::setIsDeveloperMode(true);

.htacess file
Edit the .htaccess in the Magento root directory file to add SetEnv MAGE_IS_DEVELOPER_MODE "true"
