With the test, we found our typo!

However, it did take some effort to write the test. With static typing, some of the efforts required to write test can be reduced.

The way to achieve this is to "annotate" your program with "types" so that the compiler of your program can perform its own tests.

Note that JavaScript itself does not support any type annotations. However, TypeScript supports such type annotations as an addition to plain JavaScript so that its static compiler can verify the correctness of the programs you write.

Now, take the same file as before and just rename the extension from .js to .ts .

const recipe = {

name : "tea" ,

timeToCookInMin : 2

}
