س106. What is the purpose of JSON-P (JSON with padding) in web development, and how is it typically used?

تتم محاذاة كل طبقة وهذه كلها في نفس الوقت:- JSON-P, or JSON with padding, serves the purpose of overcoming the same-origin policy limitation in web development. The same-origin policy restricts web pages from making AJAX requests to a different domain for security reasons. JSON-P works by wrapping JSON data in a JavaScript function call, allowing data to be retrieved from an external domain as if it were a script. This technique is commonly used for securely fetching data from external APIs, making it a valuable tool for cross-domain data exchange in web applications.

Q107. In a JSON document, how can you represent a key that contains special characters, such as spaces or hyphens, to ensure proper parsing and access in JavaScript?

Wrap the key in single quotes.
Enclose the key in square brackets.

Enclose the key in double quotes.

تتم محاذاة كل طبقة وهذه كلها في نفس الوقت:- When you have a key in a JSON document that contains special characters, المساحات, or hyphens, it is essential to enclose the key in double quotes. JSON requires keys to be represented within double quotes to ensure proper parsing and access in JavaScript. This ensures that JavaScript can correctly interpret keys with special characters or spaces and access their associated values.
