Sometimes, we want to create a password generator with JavaScript.
In this article, we’ll look at how to create a password generator with JavaScript.
How to create a password generator with JavaScript?
To create a password generator with JavaScript, we can get random characters from a string.
For instance, we write
const generatePassword = () => {
const length = 8;
const charset =
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
const retVal = "";
for (let i = 0, n = charset.length; i < length; ++i) {
retVal += charset.charAt(Math.floor(Math.random() * n));
}
return retVal;
};
to define the generatePassword function.
In it, we loop i from 0 to length - 1 with a for loop.
In the loop, we get a random character from the charset string with
charset.charAt(Math.floor(Math.random() * n))
We use Math.floor(Math.random() * n) to get a random number between 0 and charset.length.
And we append the selected character to the retVal string.
Then we return the string after the loop is done.
Conclusion
To create a password generator with JavaScript, we can get random characters from a string.
