Question

I have a bunch of functions that look like this

'tea' : function (caller) {
    this.speak(this.randomOption('tea_msg'));

},

'chill' : function (caller) {
    this.speak(this.randomOption('chill_msg'));

},

and what i want is to merge them to something like this

'tea' ,'chill': function (caller) {
     // get which function name was called in var lets call it fun
    this.speak(this.randomOption(fun +'_msg'));
}

Is this possible or am I going about this the wrong way?

Answer 1

[ 'tea', 'chill', 'elephant', 'moose' ].forEach(function (val) {

    //creating a closure so `val` is saved
    (function (val) {
        obj[ val ] = function ( caller ) {
            this.speak( this.randomOption(val + '_msg') );
        };
    }(val));

});

You can also write a generic say function:

say : function ( caller, type ) {
    this.speak( this.randomOption(type + '_msg') );
}
