If the regular expression remains constant, using this can improve performance.Or calling the constructor function of the RegExp object, as follows:Using the constructor function provides runtime compilation of the regular expression. I have a very similar idea, but for C# and web development. Your code so far. After completing the inner loop 1 then it goes to inner loop 2 to print the star(*) for a range of (0,6-i) and print the 6 star in the same line. The iterations are nothing but repeating some piece of code, for finite number of times until it’s condition remains true.
