    <h1>This page is for practicing Spread operator, to create shallow copies.</h1>
    <h2>Shallow Copy</h2>
    <p>The <b>spread operator</b> only creates a shallow copy, meaning it only copies the top-level properties.</p>
    <h2>Deep Copy</h2>
    <h3>1. JSON.parse(JSON.stringify(original))</h3>
    <p><b>JSON.stringify(original)</b> - This converts the object into a string.</p>
    <p><b>JSON.parse(...)</b> - This reads the string and builds a new object from it.</p>

    <h3>2. Lodash {_.cloneDeep()}</h3>
    <p>Lodash is a JavaScript helper library — it gives you many easy-to-use tools for working with arrays, objects, and other data.</p>
