create a password with at least one number in typescript

To create a password with at least one number in TypeScript, you can use regular expressions to validate the input. Here's a simple function that takes in a password string and checks if it contains at least one number:

index.ts
function validatePassword(password: string): boolean {
  const regex = /\d/;
  return regex.test(password);
}
110 chars
5 lines

In this function, \d is a regular expression that matches any digit. We use the test method to see if this pattern is present in the password string. If it is, the function returns true. Otherwise, it returns false.

You can use this function to validate user input and ensure that all passwords entered contain at least one number.
