How to generate a random hexadecimal string in TypeScript

Answer 1

function generateHex(len: number): string {
  const hexChars = '0123456789ABCDEF';
  let hexStr = '';

  for (let i = 0; i < len; i++) {
    const index: number = Math.floor(Math.random() * 16);
    hexStr += hexChars[index];
  }

  return hexStr;
}

const len: number = 8;
const hexNumber: string = generateHex(len);

console.log('Random Hexadecimal Number:', hexNumber);



/*
run:

"Random Hexadecimal Number:",  "91F117F1" 

*/
