Understanding why Semantic HTML is important, as told by TypeScript

What a great technological analogy by Mandy Michael. A reminder that TypeScript…

makes use of static typing so, for example, you can give your variables a type when you write your code and then TypeScript checks the types at compile time and will throw an error if the variable is given a value of a different type.

In other words, you have a variable age that you declare to be a number, the value for age has to stay a number otherwise TypeScript will yell at you. That type checking is a valuable thing that helps thwart bugs and keep code robust.

This is the same with HTML. If you use the <div> everywhere, you aren’t making the most of language. Because of this it’s important that you actively choose what the right element is and don’t just use the default <div>.

And hey, if you’re into TypeScript, it’s notable it just went 3.0.
