JavaScript Code:
function check_script(str)
{
if (str.length < 6) {
return str;
}
let result_str = str;
if (str.substring(10, 4) == 'Script')
{
result_str = str.substring(0, 4) + str.substring(10,str.length);
}
return result_str;
}
console.log(check_script("JavaScript"));
console.log(check_script("CoffeeScript"));

Returns the sum of the powers of all the numbers from start to end (both inclusive)
Example:
const sumPower = (end, power = 2, start = 1) => Array(end + 1 - start) .fill(0) .map((x, i) => (i + start) ** power) .reduce((a, b) => a + b, 0); console.log(sumPower(10)); // 385 console.log(sumPower(10, 3)); // 3025 console.log(sumPower(10, 3, 5)); // 2925
Output:
385 3025 2925
