  • JavaScript vs. TypeScript vs. ReasonML
    • In this blog post, I describe the pros and cons of three programming languages/dialects: JavaScript, TypeScript and ReasonML. My descriptions are based on recent experiences with TypeScript and ReasonML on a few smaller real-world projects and on years of experience with JavaScript.

  • In this blog post, I describe the pros and cons of three programming languages/dialects: JavaScript, TypeScript and ReasonML.
  • My descriptions are based on recent experiences with TypeScript and ReasonML on a few smaller real-world projects and on years of experience with JavaScript.
  • Before we take a look at the languages, lets first consider the pros and cons of static typing, given that TypeScript and ReasonML are statically typed and JavaScript isnt.
  • Conclusion: TypeScript occupies a nice middle ground between JavaScript and ReasonML.
  • The strength and variety of the JavaScript ecosystem is amazing at the moment: You can switch between JavaScript, ReasonML and TypeScript, as needed (and with varying degrees of work).

  • Lets fix it by stating we can only pass the type String as an argument to our nameToUpperCase() method.
  • Now instead of having to remember nameToUpperCase() only accepts a String, we can trust Typescript to remember it.
  • Notice TypeScript gets compiled to Javascript (its just a superset of Javascript, much like C++ toC)Thats the big-big argument why TypeScript and type checking is great.
  • Open your terminal and type the following: – We should end up with the Typescript config.
  • unorganized array vs tuple (organized array)If we dont follow the sorting index rules we issued for our tuple, Typescript will hint us we didnt go by the rules – The tuple expects the first value to be a numberbut its not in this case, its a string Indrek and thus…
