Evaluating Grade Status via Conditional Branching in Vue
Control flow structures like if, else if, and else allow executing different code blocks based on numerical conditions. In Vue, computed properties can use conditional branching to derive descriptive text labels dynamically based on reactive numeric states.

Breakdown
1
const score = ref(85);
Declares a reactive number ref holding the test score.
2
if (score.value >= 90) {
Evaluates whether the numerical value is greater than or equal to 90.
3
} else if (score.value >= 75) {
Checks the secondary threshold if the first comparison returns false.
4
} else {
Executes fallback branch when none of the previous conditions are met.
