Full Stack JavaScript Techdegree Student 9,558 PointsDifference between these 2 sets of code and why one over the other:
This code is given as part of the solution:
let listProducts = prods => {
let productNames = [];
for (let i = 0; i < prods.length; i++) {
productNames.push(prods[i].name)
}
return productNames;
}
On the other hand this is what I came up with:
let listProducts = prods => {
return prods.map(prods => prods.name)
}
console.log(listProducts(product));
Is there anything that I might be doing wrong or is there any reason why the given solution should be used. Both give the same result btw

The simple loop was probably used in this practice because it might be used by students who have not yet reached the part of the course where the more advanced map method of arrays is introduced.

Treehouse Project ReviewerHi Sufiyaan Haroon the latter is using newer ES6 syntax so it is cleaner and easier to read than the first. Your just simply seeing two ways of achieving the same outcome which is what code is all about an that is great to see! If you wanted, for the latter you can simplify it even more to make it shorter by using an implicit return:
let listProducts = prods => prods.map(prods => prods.name);
