# Running a Node.js program locally V/S Runnning an AssemblyScript program written for NEAR

## **Objective**: To help beginners understand, how contracts(programs) are deployed on NEAR while drawing comparisons from Web Development

:::info
**Note:**
This document ==assumes that the readers already have beginner level knowledge of Node.js, AssesmblyScript and NEAR==
:::

### A) Steps for locally running Node.js program::memo:

1. Write and save the program to a '.js' file
2. Run program :rocket:

$ node programFile.js

> Node.js programs are interpreted at runtime

---

### B) Steps to deploy an AssesmblyScript program(contract) written for NEAR :memo:

1. Write and save the program to a '.ts' file
2. Compile the program to a '.WASM' file :astonished:

$ yarn build:release

3. Deploy the WASM file to NEAR

$ near deploy --accountId accountname.testnet --wasmFile programFile.wasm

4. Run/ Call the program

$ near view accountname.testnet functionName

:::info
**Note:**
All further ==changes to the AssemblyScript program have to saved, re-compiled, re-deployed and re-run on NEAR==

## Summary :notebook:

| Node.js | AssemblyScript (NEAR) |
| ----------------- |:----------------------- |
| Write and save program | Write and save program |
| :negative_squared_cross_mark: | Compile program to a WASM file |
| :negative_squared_cross_mark: | Deploy the WASM file to NEAR |
| Run program | Call/ Run program(Contract) |
