Notes

1. Debugging easy definition : the process of identifying and removing errors from computer hardware or software.
   This debugging process often takes a long time, as fixing some errors may introduce others.

2. Testing easy definition: Testing is the process to find bugs and errors.
   *There is no need of design knowledge in the testing process.
   *Testing can be manual or automated.
   *Testing is initiated after the code is written.

3. Breakpoints: Breakpoints play an important role in debugging.
   They pause (break) a program when it reaches a certain point.

Questions

1. Is debugging knowledge really necessary for web developers?
   Found the answer after going back and reading more:
   Debugging is done by either programmer or developer.

Code Examples

1. var x = 15 * 5;
   debugger;
   document.getElementById("demo").innerHTML = x;
