How to use String Repeat Method In Javascript
In this approach we are using “repeat()” inbuilt function of JavaScript which takes single argument, which is the number of times the string should be repeated. In a custom function after using repeat() function we need to print that string into the console for that we are using for loop which iterates n(size) times and creating square pattern in console.
Example: It describes how we can print a square pattern star in the console using String reapeat method
Javascript
// Function for printing square pattern function printSquare(n) { const row = "* " .repeat(n); // For loop for (let i = 0; i < size; i++) { console.log(row); } } let size = 5; // Calling function printSquare printSquare(size); |

Time complexity: O(N)
Space complexity: O(1)
JavaScript Program to Print Square Star Pattern
In this article, we are going to discuss how we can make a square star pattern. we have to print “*” in the console in such a way that it turns or looks like a solid square. we can use loops in different manners for this pattern.
Example:
Input: 4
Output: * * * *
* * * *
* * * *
* * * *
Input: 3
Output: * * *
* * *
* * *
These are the following ways to print a square star pattern in the console:
- Using nested for loop
- Using for loop
- Using String Repeat Method
- Using Array and Join Method
- Using ES6 Repeat and Template Literal
