You can use a loop and traverse the string from backwards. In the below example, I'm using while loop, but you can also use for loop for the same.

```js
let str = "hello world";

let reverseString = "";
let i = str.length-1;

while(i >= 0) {
  reverseString += str[i];
  i--;
}

console.log(reverseString)
```
