Definition:
A breakpoint is a tool you can set in your program. It tells the program to stop at a certain line so you can check things like variable values, syntax, or logic.
It helps you go through the code step by step to find exactly where the error is and makes it easy to debug errors in your program.
Now you will clearly understand the code with the help of the flowchart:
Start | v Step 1: Open your code in the browser (F12 → Sources) | v Step 2: Choose the line where you want to pause the code | v Step 3: Click on that line number (Breakpoint is set) | v Step 4: Run the program | v Step 5: The code stops at the breakpoint | v Step 6: Check the values, variables, and each step | v Step 7: Find the mistake | v Step 8: Fix the error in your program | v End
Example:
let a = 4;
let b = 10;
let result = a + b; // You can set a breakpoint on this line to check the variables and their values.
console.log(result);Output:
