The static type system is essentially erased from the javascript that actually runs. Type assertion is a way of telling the compiler about a variable as a type instead of inferring the value. Type annotations will always go after the thing being typed.

In typescript, there is no typecasting, but we have type assertions. Type annotations will always go after the thing being typed.

So, Expr As Number Is A Compile Time Type Assertion, Not A Runtime Type Cast.

If you want to be more restrictive, you can use: While typescript has syntax that looks like casts, these are actually “type assertions” instead. Use the <> operator for.

Let’s Take The First Example, And Write Something Like It In Typescript:

When The As Keyword Is Used, It Informs The Compiler To Consider The Entity As Another Type Rather Than What The Compiler Thinks It Is.

(Obj As Any) = Undefined;

Now typescript will case the type to string, and we can use length. To cast something in typescript, we use the as keywords. The process of changing types is what is called “type casting”.

For This Example, We Need To Cast The Text Variable To A String, So Typescript Will Let Us Use Length:

Let value = (text as string).length; Typescript is about typings, but you always have a way to break the typing for good or bad reasons. That is, typecasting can be done by prepending the fruit variable using the type enclosed in the angle brackets as depicted below.
