How do you generate random strings or characters in JavaScript?
Hello Sakshikuchroo,
I think this will work for you:
function makeid(length) { let result = ‘’; const characters = ‘ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789’; const charactersLength = characters.length; let counter = 0; while (counter < length) { result += characters.charAt(Math.floor(Math.random() * charactersLength)); counter += 1; } return result; }
console.log(makeid(5));
Hello Sakshi,
This simple and reliable code snippet returns exactly five random characters. Unlike some other solutions, it ensures a consistent length of output.
javascript code: Math.random().toString(36).slice(2, 7);
This code generates a random number between 0 and 1 using Math.random(), converts it to a base-36 string using toString(36), and then extracts a substring of length 5 starting from index 2 using slice(2, 7). The result is a string of five characters that can include numbers (0-9) and lowercase letters (a-z).
Hey Sakshi,
here is the Answer to the Question,
When changing double quotes to single quotes in the echo command, as shown below:
echo -e ‘Hello,\nWorld!’
The output will be:
Hello, World!
This is because single quotes prevent the shell from interpreting special characters like \n, so the newline character is printed as-is.
