In JavaScript, != is the not equal operator, which returns true if the operands are not equal, and false otherwise.
There are several other comparison operators in JavaScript, including:
When using ==, JavaScript will perform type coercion if the operands are of different types (e.g. "5" == 5 returns true). On the other hand, when using ===, no type coercion is performed and the comparison will only return true if both operands have the same value and type (e.g. "5" === 5 returns false).
