WebFeb 26, 2024 · Primitive. In JavaScript, a primitive (primitive value, primitive data type) is data that is not an object and has no methods or properties. There are 7 primitive data types: Most of the time, a primitive value is represented directly at the lowest level of the language implementation. All primitives are immutable; that is, they cannot be altered. All data in computers based on digital electronics is represented as bits (alternatives 0 and 1) on the lowest level. The smallest addressable unit of data is usually a group of bits called a byte (usually an octet, which is 8 bits). The unit processed by machine code instructions is called a word (as of 2011 , typically 32 or 64 bits).
