May 6, 2024 · This article will show you how to make a triangle star pattern using JavaScript. We’ll use a for loop to iterate through the number of rows, and in each iteration we will use a for loop for the n number of iterations, and in each loop we will print the “*” with the repeat method to increase or decrease the number of stars in each iteration.

Feb 22, 2018 · You could do this as below : function makeLine(length) {. // length has the number of lines the triangle should have. var line = ""; for (var i = 1; i <= length; i++) {. // Enter the first for loop for the number of lines. for(var j=1; j<=i; j++){.

While learning programming concepts Star pattern is used to test different programming skills like looping, conditional statements, etc. The program is to display a pattern of stars. Star patterns can be created in any programming language, however here we are going to use JavaScript. It is a series of stars (*) which creates a certain pattern or g...
We are going to create 15 different star pattern program in javascript and print them. 1. Square star pattern in javascript 2. Hollow square pattern 3. Right triangle star pattern 4. Left triangle star pattern 5. Downward triangle pattern 6. Hollow triangle pattern 7. Pyramid star pattern in javascript 8. Reversed pyramid star pattern 9. Hollow pyr...
To create a square star pattern run 2 nested for loop. Execute each loop for 'n' number of times, where 'n' is number of rows/columns in the square, i.e for(let i = 0; i < n; i++). The internal loop will run for 'n' number of times which will print starts in a row and a newline at the end of the loop (\n) while the outer loop will run the internal ...
Steps to create a hollow square star patternare: 1. Create a variable to store the string and assign it with an empty string 2. Create a for loop to run for 'n' number of times, where 'n' is number of rows/columns in the square, i.e for(let i = 0; i < n; i++) 3. Inside the loop, create a for loop that prints a star (*) at the beginning and end of t...
To create a right triangle pattern in javascriptyou will have to deal with 3 loops, 1 of which is external and 2 are internal. The external loop will execute internal loops for 'n' number of times and the internal loop will design a pattern for each row. From the above pattern, you can see each row has a series of stars and spaces. The number of st...
To create the left triangle pattern in javascript again run 2 nested for loopexternal loop will take care of columns of pattern and the internal loop will print rows of the pattern. You can observe from the above-shown pattern that we need to run an external loop for 'n' time while the internal loop runs for 1 time in the first execution, 2 times i...
To create a downward triangle star pattern use a nested loop, it is also known as a reverse star pattern. From the above-shown pattern, you can see the number of stars decreases from 'n' to 1. Run a for loopinside an external loop whose number of iterations decreases from 'n' to 1.
Steps to create a hollow triangle star patternare: 1. Run 2 nested loops, 1st for 'n' times and 2nd for 1 time for the first row, 2nd for 2 times for the second row, and so on till 'n' times 2. Print star for first and last position in each row and space for other positions 3. In the last line print star at each position
The Pyramid star patternis a famous star pattern, you can see the shape of the pattern above. It uses 2 loops inside the external loop one for printing spaces and the other to print stars. The number of spaces in a row is n - i in each row and the number of stars in a row is 2 * i - 1. Also, check out alphabet patterns in JavaScript.
The reversed pyramid star patternis a pyramid pattern upside-down. It uses 2 loops inside the external loop one for printing spaces and the other to print the star. First loop prints spaces and other loop print stars. Here is the code of the reverse pyramid star pattern. The number of spaces in a row is i and the number of stars is 2 * (n - i) - 1.
Jun 17, 2024 · Steps to Print a Triangle Star Pattern. Step 1: Set Up the Loop Structure. Outer Loop: The outer loop controls the number of rows in the triangle. Inner Loop: The inner loop controls the number of stars printed in each row. Step 2: Construct the Pattern. Initialize String:
There are several patterns problems to solve, but in this shot, we will learn how to print a right triangle star (*) pattern with help of JavaScript. The right triangle pattern displays * in the form of a left triangle (right angled from the right side) on the screen or console.
Jan 16, 2024 · Printing a reverse Floyd pattern triangle pyramid involves outputting a series of numbers in descending order, forming a triangular shape with each row containing one less number than the previous row. The numbers are arranged in such a way that they form a right-angled triangle, reminiscent of Floyd's triangle, but in reverse order. Example: Input

To create a Left Triangular Star Pattern in JavaScript, you can follow these steps: Start by defining a variable to store the desired number of rows for the pattern. Implement a loop that iterates from 1 to the specified number of rows. Within the loop, employ a nested loop to print the stars on each line.
