We’ll also consistently compare it to its sibling, theanytype; if you are not familiar with it yet, check outthisarticle, where we have discussed it in more detail. What is the unknown type? InTypescript,any value can be assigned to theunknowntype, but without a type assertion,unknown...
You can fix this with TypeScript by specifying the types of each variable:let num1: number = 10; // num1 is statically typed as a number let num2: string = "20"; // num2 is statically typed as a string let result = num1 + num2; // Error: Type 'string' is not assignable ...
The final output of TypeScript is pure JavaScript. TypeScript provides classes, types, modules, inheritance, properties, and methods that are known to object-oriented programmers. TypeScript helps organizes large projects into modules and helps developers create large scale JavaScript-based ...
