An operator is used to perform task for one or more values into a single resultant output value.
// Assign values to variables and add them together: var x = 5; // assign the value 5 to x var y = 2; // assign the value 2 to y var z = x + y; // assign the value 7 to z (x + y)
An operator operates on operand or operands. The combination of one or more operators is referred to as an expression.
|%||Modulus (Division Remainder)|
console.log(5 + 4); // Prints 9 console.log(7 - 1); // Prints 6 console.log(6 * 2); // Prints 12 console.log(15 / 3); // Prints 5
console.log() the computer will evaluate the expression inside the parentheses and print that result to the console.
The remainder operator, sometimes called modulo, returns the number that remains after the right-hand number divides into the left-hand number as many times as it evenly can:
11 % 3 equals 2 because 3 fits into 11 three times, leaving 2 as the remainder.
