JavaScript Interview Questions - Double Equals (==) vs Triple Equals (===) || Type Coercion #3

Hey there, coders!
In this video, we're unraveling the mystery behind the double equals (==) and triple equals (===) operators in JavaScript. 🧐 Join us as we delve into the nuances of equality comparison, exploring when to use each operator and why it matters. Whether you're a beginner or an experienced coder, understanding the difference between these two is crucial for writing robust and bug-free code. Tune in to gain clarity and mastery over JavaScript's equality operators!

"==" checks if two values are equal, but it's not strict about data types. This means it can sometimes lead to unexpected results because it tries to convert the values to the same type before comparing them.

"===" is stricter. It not only checks if the values are equal but also ensures they are of the same data type. This makes it more reliable and less prone to unexpected behavior.

So, in simple terms:

Use "==" when you want to check if two values are equal, and you're not concerned about their data types.
Use "===" when you want to check if two values are equal and they must be of the same data type.
• If either operand is a string, the other operand will be converted to a string.
• If either operand is a number, the other operand will be converted to a number.
• If either operand is a boolean, it will be converted to a number (true becomes 1 and false becomes 0).
• If one operand is an object and the other is a primitive value, the object will be converted to a primitive value before the comparison is made.
If one of the operands is null or undefined, the other must also be null or undefined to return true. Otherwise it will return false.
