TypeScript 3.7 implemented support for assertion functions in the type system. An assertion function is a function that throws an error if something unexpected happened. Using assertion signatures, we can tell TypeScript that a function should be treated as an assertion function.
TypeScript 3.7 added support for the ?. operator, also known as the optional chaining operator. We can use this operator to descend into an object whose properties potentially hold the values null or undefined without writing any null checks for intermediate properties.
Git 1.7.12 introduced the --root flag for the rebase command that lets you rewrite all the history leading to a specific commit down to the root commit.
TypeScript 3.7 added support for the ?? operator, which is known as the nullish coalescing operator. We can use this operator to provide a fallback value for a value that might be null or undefined.
Different approaches for declaring a global variable in TypeScript.
In JavaScript, there are different approaches to concatenating multiple arrays into a single one. A comparison of push(), concat(), and spread syntax.
TypeScript 3.5 added an Omit<T, K> helper type which lets us create an object type that omits specific properties from another object type.
In this post, I want to introduce you to ripgrep, a smart and fast command line search tool that I find myself using all the time when programming.
With TypeScript 3.4, const assertions were added to the language. A const assertion is a special kind of type assertion in which the const keyword is used instead of a type name.
TypeScript 3.4 added a bit of syntactic sugar to the language that makes it easier to work with read-only array and tuple types.
