A primitive (primitive value, primitive data type) is data that is not an object and has no methods. In >JavaScript, there are 6 primitive data types: string, number, boolean, null, undefined, symbol (new in ECMAScript 2015). Most of the time, a primitive value is represented directly ...
Equality check for primitive data types likeboolean,stringandintegeris very simple since they are always compared by their actual value: 1===1’string’ === ’string’true===true On the other hand, equality check for complex types likeobjects,arraysandfunctionsis completely different. Two object...

2. Primitive TypesAccording to the ECMAScript specification, JavaScript has six primitive data types: string, number, bigint, boolean, undefined, and symbol. These types are immutable, meaning their values cannot be altered. There is also a special primitive type called null, which represents the...
nullis the only primitive value that is “falsy” (aka false-like; seeChapter 4) but which also returns"object"from thetypeofcheck. So what’s the seventh string value thattypeofcan return? typeoffunctiona(){/* .. */}==="function";// true ...
