1,300 PointsHow can I change the function to a arrow function?
I would like to change the functions in the method to an arrow function, but I did something wrong. It does not work:
methods: {
increment: function(){
this.votes += 1;
},
decrement: function(){
this.votes -= 1;
}
}
What I did
methods: {
increment: () => {
this.votes += 1;
},
decrement: () => {
this.votes -= 1;
}
}

for your solution i would use the above
