JavaScript objects must implement certain standard properties and methods. Objects have a prototype property that is either an object or null, and prototype chains must have finite length. The typeof operator returns a string indicating the type of a variable or value. JavaScript supports basic types like undefined, null, boolean, number, string, and object. Functions are objects that can be called, and have properties like length and arguments. Variables declared with var have function scope, while variables assigned without var have global scope. Arrays, objects, and functions can be declared using various syntaxes. JavaScript uses prototypal inheritance rather than classes.
