In JavaScript stored procedures, which operator checks strict equality without type coercion?

• A. ==
• B. ===
• C. !=
• D. !==

Answer: (B)

Strict equality checks both value and type, with no implicit conversion. The operator that does this is the triple equals operator (===). For example, 5 === 5 is true, but 5 === '5' is false because the types differ. This avoids surprises from automatic type coercion that happens with loose equality. The loose equality operator (==) converts operands to a common type before comparing, so 0 == '0' is true. The not-strict-equal operator (!==) is simply the negation of strict equality, returning true when operands are not strictly equal (either different type or different value). The not-equal operator (!=) also uses type coercion and checks if, after coercion, the values differ.
