How to write a function that generates random string in Javascript?
To write a function that generates a random string in JavaScript, you can use the following code:
function generateRandomString(length) { let result = ''; const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'; const charactersLength = characters.length; for (let i = 0; i < length; i++) { result += characters.charAt(Math.floor(Math.random() * charactersLength)); } return result; }
This function takes an argument length that specifies the length of the random string to generate. It generates the string by selecting random characters from a set of upper and lower case letters and numbers, and concatenating them together.
You can then use the function by calling it and passing in the desired length of the random string, like this:
const randomString = generateRandomString(10); // generates a random string of length 10
