Iterating through lists or arrays to perform calculations or transformations on each element.

Iterating through a dataset to find a specific element that satisfies a given condition.

Loops can be used to repeatedly prompt the user for input until it meets certain criteria.

Updating game state, processing user input, and rendering graphics.

Extracting data from multiple web pages by iterating through a list of URLs.

Can be used in cryptography or checking for palindromes.

1. Initialize an empty string. 2. Iterate through the original string from the last character to the first. 3. Append each character to the new string.

1. Initialize a counter variable. 2. Write the while loop condition. 3. Include the code to be executed within the loop. 4. Update the counter variable inside the loop.

1. Initialize the loop variable in the for loop declaration. 2. Define the loop condition. 3. Specify the increment/decrement operation. 4. Include the code to be executed within the loop.

1. Create a table with variables. 2. Execute each line of code. 3. Update the table with the new values. 4. Check the loop condition.

1. Iterate through the string. 2. Extract a substring of the same length as the target substring. 3. Compare the extracted substring with the target substring. 4. If they are equal, return true; otherwise, continue.

While Loop: Condition checked before each iteration, more flexible. | For Loop: Initialization, condition, and increment in one line, preferred when iterations are known.

charAt(): Returns a single character at a specified index. | substring(): Returns a new string that is a substring of this string.
