Control Statements

Control structures route program execution dynamically based on real-time runtime conditions.

1. The if...else if...else Statement Pattern

let engineSpeed: number = 75;

if (engineSpeed > 90) {
    console.log("Critical velocity threshold reached!");
} else if (engineSpeed >= 50) {
    console.log("Optimal operating efficiency.");
} else {
    console.log("Sub-optimal velocity profile.");
}

2. The switch-case Construct

The switch block evaluates a single input statement expression against multiple strictly mapped case values:

enum StatusGate {
    Pending,
    Active,
    Terminated
}

let pipelineStatus: StatusGate = StatusGate.Active;

switch (pipelineStatus) {
    case StatusGate.Pending:
        console.log("Queue buffering initialized.");
        break;
    case StatusGate.Active:
        console.log("Pipeline clearing jobs.");
        break;
    case StatusGate.Terminated:
        console.log("Flushing active memory traces.");
        break;
    default:
        console.log("Unknown pipeline execution state.");
}

3. Inline Ternary Conditional Operations

For compact assignment mechanics, use the conditional ternary syntax:

let ageLimit: number = 21;
let registrationState: string = (ageLimit >= 18) ? "Authorized" : "Denied";
