JavaScript Brain Teasers: Exercise Your Mind

Discussion: The Shape Shifter

Explore how JavaScript compares strings and objects using type coercion in this lesson. Understand why certain comparisons yield unexpected results and learn safer methods to verify string cases. This lesson helps you grasp JavaScript's type coercion quirks and improve your problem-solving skills to write clearer code.

We'll cover the following...

Verifying the output

Now, it’s time to execute the code and observe the output.

Javascript (babel-node-es2024)
const a = "f"<{};
const b = "F"<{};
console.log(a);
console.log(b);

Type coercion

In JavaScript, when we use the < operator to compare values, it performs a process called type coercion to convert the values into a common type before making the comparison.

Understanding the output

In this code snippet, we have a string F on the left side and an empty object {} on the right side. JavaScript ...
