@mrmr I got this example of a book.
Instead of simple parameters, the function is called by the ".call" and the parameters are used by "this." keyword inside the function. -
@brunofontes Ah I see, a pretty bad example as it doesn't provide a valid use case.
My confusion was around the fact that using call in that example was completely unnecessary 😂
What only relying on JavaScript for HTML form input validation looks like
Found something true as 1 == 1
function normalize() {
console.log(this.coords.map(n => n / this.length));
}
normalize.call({coords: [0, 2, 3], length: 5});
Why? Why, javascript? Why do you invert the function and the 'this' keyword? It just confuses me and (at this time) I cannot think of a place where this would be really necessary.
