How to use 2D matrix In Javascript
In this approach, we have used the simple logic of iteration over lines to create the pattern G. We will use the conditions to print stars at particular positions which creates the G pattern.
Example: The below example uses the 2D matrix to print the pattern ‘G’ in JavaScript.
Javascript
function printPatternG(line) { for (let i = 0; i < line; i++) { let row = ''; for (let j = 0; j < line; j++) { if ((j == 1 && i != 0 && i != line - 1) || ((i == 0 || i == line - 1) && j > 1 && j < line - 2) || (i == Math.floor((line - 1) / 2) && j > 2 && j < line - 1) || (j == line - 2 && i != 0 && i >= Math.floor((line - 1) / 2) && i != line - 1) ) row += "*"; else row += " "; } console.log(row); }}printPatternG(7) |

JavaScript Program to Print the Pattern G
This program aims to print the pattern ‘G’ using asterisks (*) in the console output. The pattern ‘G’ consists of several horizontal and vertical lines arranged to form the uppercase letter ‘G’. It requires careful positioning of asterisks to represent the shape accurately.
Below are the methods to print the G pattern:
