In TypeScript it is possible to reverse string in following way.

1. Reverse string with split-reverse-join operations example

Edit

xxxxxxxxxx
 
function reverseString(text: string): string {
  const characters: string[] = text.split('');
  const reversion: string[] = characters.reverse();
  return reversion.join('');
}
​
// Usage example:
​
const text: string = 'This is my text...';
const reversion: string = reverseString(text);
​
console.log(reversion); // ...txet ym si sihT

Output:

xxxxxxxxxx
 
...txet ym si sihT

2. Reverse string with iteration example

Edit

xxxxxxxxxx
 
function reverseString(text: string): string {
  let result: string = '';
  for (let i = text.length - 1; i > -1; --i) {
    result += text[i];
  }
  return result;
}
​
// Usage example:
​
const text: string = 'This is my text...';
const reversion: string = reverseString(text);
​
console.log(reversion); // ...txet ym si sihT
