TypeScript is a popular programming language that is a superset of JavaScript. It provides optional static typing, interfaces, and other features that help to improve the scale and maintainability of JavaScript code.
In this article, we'll be discussing the import exec ts
command, which is a useful way to execute TypeScript code without having to compile it first.
import exec ts
To use import exec ts
, first, you need to install the ts-node
package. You can do this by running the following command:
npm install -g ts-node
Once you've done that, you can use import exec ts
in your TypeScript files to import other TypeScript files and execute them.
Here's an example:
```typescript
// file1.ts
import { add } from "./file2.ts";
console.log(add(2, 3)); // Output: 5
```
```typescript
// file2.ts
export function add(a: number, b: number): number {
return a + b;
}
```
```typescript
// index.ts
import "./file1.ts";
// Output: 5
```
In this example, we have three files: file1.ts
, file2.ts
, and index.ts
. file1.ts
imports the add
function from file2.ts
and then calls it with the arguments 2
and 3
. index.ts
then imports file1.ts
and executes it, resulting in the output 5
.
import exec ts
is a useful command that allows you to execute TypeScript code without having to compile it first. It's a great way to quickly test out code and prototype new features. If you're already using TypeScript, then you should definitely give it a try!
