Sample text
X = x; } } This is a very common scenario in TypeScript, and one can simply prefix the member using an access modifier and this will be declared automatically in the class and then copied from your constructor. log(rest); } allFunction (‘sample’, ‘bar’); // [] allFunction (‘sample’, ‘bar’, ‘bas’, ‘qux’); // [‘bas’,‘qux’] Chapter 7- Destructuring Destructuring means breaking up the structure. The following types of destructuring are supported in TypeScript: 1. Object Destructuring 2. The example given below shows how structuring can be done in JavaScript: var myVar = { bar: { bas: 789 } }; With the support for structuring in JavaScript, the process of creating new objects would have been a bit tough.
Chapter 8- for…of The “for…of” does not iterate over the elements of an array, and this is a common problem experienced by JavaScript beginners. log(item); // 0,1,2 } In the above example, although we expect to get 7, 2, 5, we will get the indexes which are 0, 1, 2. Tihs is why the “for…of” was introduced in TypeScript. log(item); // 7,2,5 } The above example will output the result which you expect rather than the indexes. log(char); // are you the one looking for me?
2. private: not available for access outside class. 3. protected: available on the child classes, but not on the instances directly. c; // okay } } As you are aware, the above modifiers will work for both member properties and the member functions. x = x; } } This is a very common scenario in TypeScript, and one can simply prefix the member using an access modifier and this will be declared automatically in the class and then copied from your constructor. log(rest); } allFunction (‘sample’, ‘bar’); // [] allFunction (‘sample’, ‘bar’, ‘bas’, ‘qux’); // [‘bas’,‘qux’] Chapter 7- Destructuring Destructuring means breaking up the structure.
