Example
Some teams find that they want to leave console log statements in their code, but not have them display in production. They will override the logging functions if a variable isn't set (possibly an environment variable). Additionally, this may qualify as a security feature in some situations.
if (!DEBUG_MODE_ON) {
console = console || {};
console.log = function(){};
console.log = function(){};
console.error = function(){};
console.count = function(){};
console.info = function(){};
}
