+
+// Assignment Operators
+// Used to assign values to variables.

+x **= 3; // x = x ** 3 &#10141; 0
+
+// Comparison Operators
+// Used to compare values.
+console.log(10 == "10"); // Equal (checks value) &#10141; true
+console.log(10 === "10"); // Strict Equal (checks value & type) &#10141; false
