Variables in JavaScript

• Variables are like containers that hold information (data) in your code.
• This data can be numbers, text, or even more complex data structures.
• JavaScript allows you to:
  • Declare variables: Create a named container to store data.
  • Assign values: Put data into the container.
  • Manipulate values: Change the data stored in the container (e.g., perform calculations).

Example variables

let name = "John";
let age = 25;
let isPatient = true;
let conditions = ["diabetes", "cataracts", "hyperlipidaemia"];

The role of Javascript in frontend healthcare applications.

• Many modern clinical applications rely heavily on JavaScript for their functionality.
• Examples:
  • Electronic Health Records (EHRs): Dynamic forms, patient data validation, interactive dashboards.
  • Telehealth Platforms: Real-time video conferencing, chat features, remote patient monitoring.
  • Medical Imaging Software: Interactive image viewing, annotation tools, 3D visualizations.
  • Decision Support Tools: Calculate risk scores, provide treatment recommendations, display interactive charts.
• Modern JavaScript frameworks like React, Angular, and Vue.js are used to build complex and scalable web applications.
