Day five of the JavaScript class. I shared the topics and what I learned today, focused on conditional structures and how to assign grades based on the score.
General grading rule: if the score is greater than or equal to 50, a grade is assigned; otherwise, there is no grade.
Flowchart: in class, I used a flowchart to visualize decisions and jumps between conditions.
Example of explanatory JavaScript code without quotes:
let mark = value; // replace value with the actual score if (mark >= 50) { if (mark >= 90) { console.log(Aplus) } else if (mark >= 75) { console.log(A) } else { console.log(B) } } else { console.log(NoGrade) }
Explanation: first, it checks whether the score is greater than or equal to 50. If not, the result is no grade. If yes, higher ranges are checked to determine A plus, A, or B. It is important to order the conditions from highest to lowest to prevent a broader condition from capturing cases that should correspond to a higher grade.
Learnings: better handling of nested ifs, flow control with diagrams, and practice presenting clear results based on numeric ranges.
