Name
Introduced
Meaning
Addition
JavaScript 1.0
v1 + v2
Sum of v1 and v2.
(Concatenation of v1 and v2, if either operand is a string.)
Subtraction
JavaScript 1.0
v1 - v2
Difference between v1 and v2.
Multiplication
JavaScript 1.0
v1 * v2
Product of
v1
and
v2
.
Division
JavaScript 1.0
v1 / v2
Quotient of v2 into v1.
v1 % v2
Modulus
JavaScript 1.0
Integer remainder of dividing v1 by v2.
Prefi x increment
JavaScript 1.0
++v1 * v2
(v1 + 1) * v2
.
Note:
v1
will be left as
v1 + 1.
Postfi x increment
JavaScript 1.0
v1++ * v2
(v1 * v2); v1 is then incremented by 1.
