This is the fifth project of freeCodeCamp "Front End Libraries Projects" Certification

- ReactJS: frontend library (set up with create-react-app)
- SASS: CSS pre-processors
- Web Animations API
- setTimeout and setInterval: API to schedule timer-based callbacks
You can use any mix of HTML, JavaScript, CSS, Bootstrap, SASS, React, Redux, and jQuery to complete this project. You should use a frontend framework (like React for example) because this section is about learning frontend frameworks. Happy coding!
| US | Description |
|---|---|
| #1: | I can see an element with id="break-label" that contains a string (e.g. "Break Length"). |
| #2: | I can see an element with id="session-label" that contains a string (e.g. "Session Length"). |
| #3: | I can see two clickable elements with corresponding IDs: id="break-decrement" and id="session-decrement". |
| #4: | I can see two clickable elements with corresponding IDs: id="break-increment" and id="session-increment". |
| #5: | I can see an element with a corresponding id="break-length", which by default (on load) displays a value of 5. |
| #6: | I can see an element with a corresponding id="session-length", which by default displays a value of 25. |
| #7: | I can see an element with a corresponding id="timer-label", that contains a string indicating a session is initialized (e.g. "Session"). |
| #8: | I can see an element with corresponding id="time-left". NOTE: Paused or running, the value in this field should always be displayed in mm:ss format (i.e. 25:00). |
| #9: | I can see a clickable element with a corresponding id="start_stop". |
| #10: | I can see a clickable element with a corresponding id="reset". |
| #11: | When I click the element with the id of reset, any running timer should be stopped, the value within id="break-length" should return to 5, the value within id="session-length" should return to 25, and the element with id="time-left" should reset to it's default state. |
| #12: | When I click the element with the id of break-decrement, the value within id="break-length" decrements by a value of 1, and I can see the updated value. |
| #13: | When I click the element with the id of break-increment, the value within id="break-length" increments by a value of 1, and I can see the updated value. |
| #14: | When I click the element with the id of session-decrement, the value within id="session-length" decrements by a value of 1, and I can see the updated value. |
| #15: | When I click the element with the id of session-increment, the value within id="session-length" increments by a value of 1, and I can see the updated value. |
| #16: | I should not be able to set a session or break length to <= 0. |
| #17: | I should not be able to set a session or break length to > 60. |
| #18: | When I first click the element with id="start_stop", the timer should begin running from the value currently displayed in id="session-length", even if the value has been incremented or decremented from the original value of 25. |
| #19: | If the timer is running, the element with the id of time-left should display the remaining time in mm:ss format (decrementing by a value of 1 and updating the display every 1000ms). |
| #20: | If the timer is running and I click the element with id="start_stop", the countdown should pause. |
| #21: | If the timer is paused and I click the element with id="start_stop", the countdown should resume running from the point at which it was paused. |
| #22: | When a session countdown reaches zero (NOTE: timer MUST reach 00:00), and a new countdown begins, the element with the id of timer-label should display a string indicating a break has begun. |
| #23: | When a session countdown reaches zero (NOTE: timer MUST reach 00:00), a new break countdown should begin, counting down from the value currently displayed in the id="break-length" element. |
| #24: | When a break countdown reaches zero (NOTE: timer MUST reach 00:00), and a new countdown begins, the element with the id of timer-label should display a string indicating a session has begun. |
| #25: | When a break countdown reaches zero (NOTE: timer MUST reach 00:00), a new session countdown should begin, counting down from the value currently displayed in the id="session-length" element. |
| #26: | When a countdown reaches zero (NOTE: timer MUST reach 00:00), a sound indicating that time is up should play. This should utilize an HTML5 audio tag and have a corresponding id="beep". |
| #27: | The audio element with id="beep" must be 1 second or longer. |
| #28: | The audio element with id of beep must stop playing and be rewound to the beginning when the element with the id of reset is clicked. |
