What Happens When You Compare Strings and Numbers and Understanding JavaScript Type Conversion in Comparisons with Real Examples.

Our Javascript Code:

console.log("2" > "10");
console.log("2" > 10);

---

1. First Line

console.log("2" > "10");

• Both "2" and "10" are strings. (Because they are inside quotes "...", they are treated as text, not numbers.)
• When you compare two strings using >, JavaScript does NOT convert them to numbers automatically.
• Instead, it compares them alphabetically, character by character, just like in a dictionary!

---

So how does it compare "2" and "10"?

• First, it looks at the first character of each string.
• In "2", the first (and only) character is '2'.
• In "10", the first character is '1'.
• It compares '2' and '1'.
• Now remember: in Unicode/ASCII order, ASCII code of '2' is 50 and '1' is 49.

✅ So 50 > 49 is true!

Important note: It doesn’t care that 10 is "bigger" than 2 mathematically because it is comparing strings alphabetically, not numbers!

2. Second Line

console.log("2" > 10);

• Here, "2" is a string, but 10 is a number.
• When you compare a string and a number, JavaScript automatically converts the string to a number (this is called type coercion).
• So "2" becomes 2 (a number), and then it compares:

        2 > 10

• And obviously, 2 is not greater than 10, so:

It returns false.

✔ Final Answer:

A) true false
