Question

Hello fellow programmers :D

I have a little issue, this is a prep for an upcoming test, I have a wizard named Gorrok and I want him to cast a spell with the getSpell function, and I want it to be a random spell from the array I made called spells, I implemented the math.random method, for some reason it's telling me its 'undefined' is it possible that someone can find the solution and explain it to me! This isn't for marks its just for practice.

let wizardMan = {};

wizardMan.first_name = "Gorrok: ";

spells  = ['abracadabra', 'cadabraabra', 'wooz'];

var randomSpell = [Math.floor(Math.random()*spells.length)];

wizardMan.getSpell = function(){

     

    console.log(this.first_name + '  ' + this.spells);

    return this.first_name + '  ' + this.spells;

}

wizardMan.getSpell();

Answer 1

Remove the this keyword from spells, spells is global variable and not part of this

wizardMan.getSpell = function(){

console.log(this.first_name + ' ' + spells);

return this.first_name + ' ' + spells;

}

SEE OUTPUT

> wizardMan.getSpell = function() { console.log(this.first_name + ' ' + spells); return this.first name + ' ' + spells; < f () { console.log(this.first_name + ' ' + spells); return this.first_name + ' ' + spells; > wizardMan.getSpell(). Gorrok: abracadabra, cadabraabra, wooz < "Gorrok: abracadabra, cadabraabra, wooz"

Thanks, PLEASE COMMENT if there is any concern.
