Show Notes 04:50 - Regex indicies New d flag in a regex https://regex101.com/ This will tell you the indexes (indicies) of the regex matches Handy if you need to highlight or replaces matches in a string We can ask for the start and end positions of each matched capture group 07:16 - Class updates Private fields Properties and Methods to be kept private Prefix them with a # =Helpful for internal state and methods which should not be accessed directly or at all by external In React how we have __INTERNTAL_NEVER USE THIS class ColorButton extends HTMLElement { // All fields are public by default color = "red" // Private fields start with a #, can only be changed from inside the class #clicked = false } const button = new ColorButton() // Public fields can be accessed and changed by anyone button.color = "blue" // SyntaxError here console.log(button.#clicked) // Cannot be read from outside button.#clicked = true // Cannot be assigned a value from outside Getters and setters introduced in es5 https://www.w3schools.com/js/js_object_accessors.asp class Person { #hobbies = ['computers'] get #hobbiesGetter() { return this.#hobbies } #getHobbies() { return this.#hobbies } getHobbiesPublic() { return this.#hobbies } } const scott = new Person(); scott.#getHobbies(); // doesn't work scott.getHobbiesPublic(); // works 09:07 - Class fields This may seem super old because we have been polyfilling it forever Right now if you want an instance field on a class, you need to declare it in the constructor Now we can just declare them inside the class 10:36 - Static fields and methods As above can also be static with the static keyboard Works for methods too Explain what a static method is 13:17 - Top level await So handy in modules. Need to pull in some data? Simple. 15:19 - Ergonomic brand checks for private fields Used for checking if a private field on a class exists using the in keyword 16:00 - .at() method Strings and arrays - we can use square brackets to reference items of the array Super handy for grabbing the last item of an array // 🔥 New .at() method on arrays and strings const toppings = ['pepperoni', 'cheese', 'mushrooms']; // The old way to grab the last item toppings[toppings.length - 1]; // mushrooms // using .at() method with a negative index toppings.at(-1); // mushrooms // works with any index toppings.at(0); // pepperoni toppings.at(-2); // cheese // and with strings! 'Meeting Room: B'.at(-1) // B Why not use array[-1]? We used to use slice(-1) What about indexOf? 21:34 - Handy hasOwn method https://github.com/tc39/proposal-accessible-object-hasownproperty 24:51 - Class static block A static block allows you to run code before creating an optional static property during initialization https://github.com/tc39/proposal-class-static-block Links https://github.com/tc39/proposals/blob/master/finished-proposals.md ××× SIIIIICK ××× PIIIICKS ××× Scott: Ultraloq Smart Lock Wes: Magnatiles Shameless Plugs Scott: Web Components Course - Sign up for the year and save 25%!
