function sumame(arr){
console.log('Inicio del programa')
var sum = 0;
for (i=0; i < arr.lenght; i++){
console.log("Inicio del ciclo")
sum = sum + arr[i];
console.log(`Ahora sum es ${sum}`)
}
console.log(`Finalmente sum es ${sum}`)
return sum;
}

You wrote "arr.lenght" instead of "arr.length".
Also, while "sum = sum + arr[i]" is fine, you might like to know that there is a shorthand version that does the same thing: "sum += arr[i]".

console.log(arr.lenght);
before the loop and tell if it shows a valid value. Or post an example array to be sure that it is valid.
Also don't omit the ";"-characters after your statements. They might cause the error as well. So write in the loop:
console.log("Inicio del ciclo");
sum = sum + arr[i];
console.log(`Ahora sum es ${sum}`);
