What is the difference between the equality operators == and ===?

Answer

Triple equals (===) checks for strict equality, which means both the type and value must be the same. Double equals (==) on the other hand first performs type coercion so that both operands are of the same type and then applies strict comparison.

Good to hear

• Whenever possible, use triple equals to test equality because loose equality == can have unintuitive results.
• Type coercion means the values are converted into the same type.
• Mention of falsy values and their comparison.
