Utilize the console.log function with the apply method

I have a goal of creating a logging proxy that adds a specific prefix to each log statement.

What I aim to accomplish is:

customDebug("xxx","yyy");

which translates to:

console.debug("prefix","xxx","yyy");

My attempt at implementing this is as follows:

prefixLogArguments: function(arg) {
    var array = _.toArray(arg);
    array.unshift( this.getPrefix() );
    return array;
},

customDebug: function() {
    var argArray = this.prefixLogArguments(arguments);
    console.debug.apply(undefined, argArray );
},

However, the error 

Uncaught TypeError: Illegal invocation
is raised indicating that native code cannot be invoked using apply/call, even with an undefined context.

If anyone has suggestions on how to achieve this, please let me know.

As a workaround, I can use console.debug(argArray); which is not ideal since it logs an array instead of individual arguments.

Answer №1

For optimal functionality, it is recommended to provide 'console' as the context for apply :

var customDebug = function() {
    console.debug.apply(console, arguments);
};

Answer №2

Give this a shot:

console.info.apply(console, argumentsArray);
