gotcha Preset uses @babel/preset-env internally; options like targets and modules are passed through. Incorrect options may cause unexpected transpilation. ↓

fix Refer to @babel/preset-env documentation for valid options

gotcha TypeScript support requires @babel/preset-typescript to be installed separately. ↓

fix npm install --save-dev @babel/preset-typescript

deprecated useBuiltIns: 'usage' with corejs: 3 is recommended, but older settings may cause duplicate polyfills. ↓

fix Update to corejs: 3 and useBuiltIns: 'usage'

Imports

default

wrong

import preset from 'babel-preset-pob-env'

correct

module.exports = require('babel-preset-pob-env')

CommonJS module; use require() or configure in .babelrc

presetEnv
wrong
```
presets: [require('babel-preset-pob-env')]
```
correct
```
// Add to babel.config.js: presets: ['babel-preset-pob-env']
```

const { getTargets } = require('babel-preset-pob-env')

ESM import may not work if module is CJS; use default import workaround
