Thinking of the new operation of JavaScript

Some thoughts on javascript new operations:

Scenario 1:

function Test1 () {

return {name: ' Test1 '};

};

Result of new test1: {name: ' Test1 '}

Scenario 2:

function Test2 () {

};

Test2.prototype={name: ' Test2 '};

Result of new test2: {name: ' Test2 '}

Scenario 3:

function Test3 () {

return {name: ' Test3-1 '};

};

Test3.prototype={name: ' Test3-2 '};

Result of new test3: {name: ' Test3-1 '}

Scenario 4:

function Test4 () {

Return ' test4 ';

};

Result of new test4: {}

Scenario 5:

function Test5 () {

return [];

};

Results of new TEST5: [];

Scenario 6:

function Test6 () {

return function () {return ' Test6 '};

};

New Test6 Result: function () {return ' Test6 '};

Conclusion:

Unlike Java, JavaScript's new operation has a return value, and the return value can be an object, an array, a function, or, if the return value type does not meet the requirements, a shallow clone of the prototype is returned, otherwise the return value object is returned.

Questions:

In the original

Constructor Pointer   instance.  =Singleton;

This line of removal seems to be correct ...
