@JaySODec 05.2022 — #In JavaScript, the == operator is known as the loose equality operator, while the === operator is known as the strict equality operator. The main difference between the two is that the == operator will perform type coercion (implicitly convert the operand to the same type) before making the comparison, while the === operator will not. This means that the == operator will compare two values for equality after converting them to the same type, while the === operator will compare two values for equality without converting them to the same type.
In this code, the first console.log statement compares the number 1 and the string '1' using the == operator, which performs type coercion. Since the == operator converts the operands to the same type before making the comparison, the comparison evaluates to true because the number 1 and the string '1' have the same value after being converted to the same type.
On the other hand, the second console.log statement compares the number 1 and the string '1' using the === operator, which does not perform type coercion. Since the === operator compares the operands without converting them to the same type, the comparison evaluates to false because the number 1 and the string '1' have different types and are not equal.
In general, it is recommended to use the === operator for comparisons in JavaScript because it is more strict and reliable than the == operator. Using the === operator will avoid any unintended type conversions and ensure that two values are equal only if they have the same value and type. However, in some cases, you may want to use the == operator for its ability to perform type coercion, but you should use it with caution and make sure that the type conversions are intentional and desired.
