Daftar yang sudah dipelajari?
- penggunaan API Node (fs, os)
- penggunaan modul pihak ketiga (lodash, yargs)
- penggunaan JSON
- try-catcn
- arrow function
- `filter()` ES6 function
## Penting di ingat
- Cara import / require
```javascript
typeVariable namaVariable = require('directory')
=> const _ = require('lodash')
```
- Cara export module
```javascript
var funcA = () => {
console.log('function A');
}
var funcB = () => {
console.log('function B');
}
/* export the modules.. */
module.exports = {
funcA,
funcB
}
```
- Handle the error using `try-catch`
```javascript
try {
/* doing something */
} catch (error) {
/* IF fails, catch will handle it! */
}
```
- Filter array using `.filter()` and `find()`
```javascript
let names = ['indra', 'kusuma', 'jaya'];
let filteredNames = names.filter((name) => name !=='indra');
let findName = names.find((name) => name === 'indra');
console.log(filteredNames)
// ['kusuma','jaya']
console.log(findName)
// indra
```
- Filter Documentation at: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter
- Find documentation: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find
- ChromeDev Tools, open via console
``` javascript
node --inspect-brk file-location.js
/* STEP selanjutnya
- Open Chrome
- Open link 'chome://inspect'
- Then open devTools -> Open Dedicated DevTools for Node
*/
```
- JSON
`JSON.stringify` untuk merubah object jadi ke string type, kebalikanya adalah `JSON.parse` yaitu merubah string ke bentuk object
