Java

class Index {
    public static void main(String[] args) {

        for (int i=1; i<=5; i++) {
            for (int j=1; j<=i; j++) {
                System.out.print("* ");
            }
            System.out.println();
        }
    }
}

JavaScript

for (let i=1; i<=5; i++) {
    for (let j=1; j<=i; j++) {
        process.stdout.write("* ");
    }
    console.log();
}

Python

for i in range(1, 6):
    print("* " * i)
