Learn how JavaScript manages logic and repetition.

For Loops Use for loops to repeat tasks.

• Initialization: sets your starting point.
• Condition: decides if the loop keeps running.
• Afterthought: changes the counter after each turn.

Example: for (let i = 1; i <= 5; i++) { console.log(i); }

do...while Loops These loops run the code first. They check the condition second. The code runs at least once.

Example: let x = 10; do { console.log("Hello"); } while (x < 5);

Functions Functions keep your code clean.

• Parameters: names used inside the function.
• Arguments: actual values you send to the function.

Example: function add(a, b) { console.log(a + b); } add(10, 20);

Interview Tip Pass only one argument to a function expecting two. add(10); The result is NaN. The second value is undefined.
