// program to generate random strings
const characters ='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
function generateString(length)
{
let result = ' ';
const charactersLength = characters.length;
for ( let i = 0; i < length; i++ )
{
result += characters.charAt(Math.floor(Math.random() * charactersLength));
}
return result;
}
console.log(generateString(10));
console.log(generateString(10));
console.log(generateString(10));
When you run this you will see something like this, here are 3 runs as above
