Concept & Numbers
Police & Emergencies
In the United States, 911 is the main emergency number for police, fire, and medical help. Non‑emergency lines are used for situations that are important but not life‑threatening.

Safety Info
- 911 — life‑threatening emergencies: serious injury, crime in progress, fire, or immediate danger.
- Non‑emergency police numbers — noise complaints, past‑tense reports, or questions for local departments.
- Poison control and other hotlines — special help for specific emergencies.
- Always follow local guidance and teach children to use these numbers responsibly.

Code & Practice
JS Data
JavaScript can store emergency numbers as data and choose which number to show based on the situation.
const emergencyNumbers = [
{ name: "Emergency (Police / Fire / Medical)", phone: "911", type: "emergency" },
{ name: "Non‑Emergency Police (example city)", phone: "(555) 123‑4567", type: "police" },
{ name: "Poison Control", phone: "1‑800‑222‑1222", type: "medical" }
];
function chooseNumber(reason) {
if (reason === "life‑threatening") return emergencyNumbers[0];
if (reason === "noise" || reason === "report") return emergencyNumbers[1];
return emergencyNumbers[2];
}
console.log(chooseNumber("noise"));
