"=" is assigning a value: x = 5 (x is now equal to 5), x = 76.93 (x is now equal to 76.93), "==" checks if the values are equal: 5 == 76 (false because 5 is not equal to 76), 1 == true (true because 1 is equivalent to the value of true), 76.93 == "76.93" (true as even though they are have different data types the value are still equal) also just to add on there is also "===" which checks the value and data type: "5" === 5 (false as they hold the same value but are different data types) 1 === true (false for the reason as above) "hello" === "bye" (false as they are the same data type but hold different values) x = 10; x === 10 (true as x holds the exact same value and data type) 455436 === 455436 (true as they are the same value and data type)
