You could note the following:
|
|
|
|
```js no-beautify
|
|
function pow(x,n) // <- no space between arguments
|
|
{ // <- figure bracket on a separate line
|
|
let result=1; // <- no spaces before or after =
|
|
for(let i=0;i<n;i++) {result*=x;} // <- no spaces
|
|
// the contents of { ... } should be on a new line
|
|
return result;
|
|
}
|
|
|
|
let x=prompt("x?",''), n=prompt("n?",'') // <-- technically possible,
|
|
// but better make it 2 lines, also there's no spaces and missing ;
|
|
if (n<=0) // <- no spaces inside (n <= 0), and should be extra line above it
|
|
{ // <- figure bracket on a separate line
|
|
// below - long lines can be split into multiple lines for improved readability
|
|
alert(`Power ${n} is not supported, please enter an integer number greater than zero`);
|
|
}
|
|
else // <- could write it on a single line like "} else {"
|
|
{
|
|
alert(pow(x,n)) // no spaces and missing ;
|
|
}
|
|
```
|
|
|
|
The fixed variant:
|
|
|
|
```js
|
|
function pow(x, n) {
|
|
let result = 1;
|
|
|
|
for (let i = 0; i < n; i++) {
|
|
result *= x;
|
|
}
|
|
|
|
return result;
|
|
}
|
|
|
|
let x = prompt("x?", "");
|
|
let n = prompt("n?", "");
|
|
|
|
if (n <= 0) {
|
|
alert(`Power ${n} is not supported,
|
|
please enter an integer number greater than zero`);
|
|
} else {
|
|
alert( pow(x, n) );
|
|
}
|
|
```
