Less code for capitalizedFruit or less reusable?

const fruits = ['apple', 'pear', 'cherry'];
let capitalizedFruits = [];

fruits.forEach(fruit => {
  capitalizedFruits.push(fruit.toUpperCase())
})
console.log(capitalizedFruits)

Is this just as good as what was shown in the video but with less code or is it better to put the fruit toUpperCase() prior to pushing them?

Hi,
if the case is to shorten your code, so try this 

let fruits = ['apple', 'pear', 'cherry'].map(c => c.toUpperCase())
console.log(fruits)

I think thats a matter of readabilty, not that is worse or better, just personal preference

const fruits = ['apple', 'pear', 'cherry'];
let capFruits =[];
fruits.forEach( fruit=> {
  let capital = fruit.charAt(0).toUpperCase()+fruit.slice(1);
  capFruits.push(capital);
});

I would use something like this personally. So that it makes all first letters capital so you dont accidentally miss a name and it also only makes the first letter capital which would make more sense.
