JavaScript includes operators that perform some operation on single or multiple operands (data value) and produce a result. JavaScript includes various categories of operators: Arithmetic operators, Comparison operators, Logical operators, Assignment operators, Conditional operators.
It's a modulo operator. See this documentation or the specification for more information on JavaScript arithmetic operators.
% (Modulus)
The modulus operator is used as follows:
var1 % var2
The modulus operator returns the first operand modulo the second operand, that is, var1 modulo var2, in the preceding statement, where var1 and var2 are variables. The modulo function is the integer remainder of dividing var1 by var2. For example, 12 % 5 returns 2. The result will have the same sign as var1; that is, −1 % 2 returns −1.
