The inequality operator (!=) compares values for inequality after converting both values to a common type. Hence, 10 is equal to '10', making the result false.
The strict inequality operator (!==) compares values without converting types. Since 10 is a number and '10' is a string, they are not strictly equal, making the result true.
The less than or equal to operator (<=) compares whether the left operand is less than or equal to the right operand. Hence, 5 is not less than or equal to 4.
