### TypeScript Circular Definition Error Example

Source: https://github.com/juliapluto/pluto.jl/blob/main/frontend/imports/README.md

Illustrates a broken TypeScript scenario where a wrapper file's name causes a circular definition error when importing from the same module.

```typescript
// inside lodash.d.ts — BROKEN: TypeScript resolves "lodash" back to this very file
import _ from "lodash"
export default _
```

--------------------------------

### Build Frontend Distribution

Source: https://github.com/juliapluto/pluto.jl/blob/main/frontend/imports/README.md

PLUTO_PORT=2345 npm run test
```

--------------------------------

### Create New Language JSON File

Source: https://github.com/juliapluto/pluto.jl/blob/main/frontend/lang/README.md

This snippet shows the initial structure for a new language JSON file. Replace 'Ελληνικά' with the name of your language in its native script.

```json
{
    "t_language_name": "Ελληνικά"
}
```

--------------------------------

### Run Tests with Browser View Enabled

Source: https://github.com/juliapluto/pluto.jl/blob/main/test/frontend/README.md

Runs the frontend tests with the browser visible, useful for debugging. The HEADLESS=false environment variable controls this behavior.

```bash
clear && HEADLESS=false PLUTO_PORT=1234 npm run test
```

--------------------------------

### Synchronize Language JSON Files

Source: https://github.com/juliapluto/pluto.jl/blob/main/frontend/lang/README.md

Run this script to update language JSON files with new keys from the English file. This ensures all translatable strings are present.

```julia
julia update_languages.jl
```

--------------------------------

### Pluto.jl Welcome Message

Source: https://github.com/juliapluto/pluto.jl/blob/main/frontend/editor.html

This snippet displays the welcome message for Pluto.jl, including the project name and contributors.

```javascript
console.log( "Pluto.jl, by Fons van der Plas (https://github.com/fonsp), Mikołaj Bochenski (https://github.com/malyvsen), Michiel Dral (https://github.com/dralletje), Παναγιώτης (Panagiotis) Γεωργακόπουλος (https://github.com/pankgeorg), Paul Berg (https://github.com/Pangoraw) and friends 🌈" )
```

--------------------------------

### Displaying Output Instead of Using `display`

Source: https://github.com/juliapluto/pluto.jl/wiki/⚡-Writing-and-running-code

In Pluto.jl, simply output the value you want to show. The last subexpression in a block is the output value. Avoid using `display()` for notebook output.

```julia
begin
    x = 25.0
    display(sqrt(x))
end
```

```julia
begin
    y = 0.1
    display(cos(y))
    display(sin(y))
end
```

```julia
begin
    x = 25.0
    sqrt(x)
end
```

```julia
begin
    y = 0.1
    cos(y), sin(y)
end
```

--------------------------------

### Run Specific Test Suite

Source: https://github.com/juliapluto/pluto.jl/blob/main/test/frontend/README.md

Executes a particular test suite by appending the suite name with the -t flag. This allows for focused testing.

```bash
clear && HEADLESS=false PLUTO_PORT=1234 npm run test -- -t=PlutoAutocomplete
```

--------------------------------

### Corrected TypeScript Dependency Naming Convention

Source: https://github.com/juliapluto/pluto.jl/blob/main/frontend/imports/README.md

Demonstrates the correct naming convention using a suffix to avoid TypeScript circularity issues when wrapper filenames might collide with npm package names.

```typescript
lodash-es.js   ← wrapper; imports from cdn.jsdelivr.net/npm/lodash@…/+esm
lodash-es.d.ts ← type stub; imports from "lodash" (@types/lodash) without any circularity
```

--------------------------------

### Using the t function for translations

Source: https://github.com/juliapluto/pluto.jl/blob/main/frontend/lang/README.md

Demonstrates the correct way to use the `t` function for translatable strings in JavaScript, instead of direct string literals in functions like `confirm`.

```js
if(confirm(t("t_delete_cell_confirm"))) {
    // ...
}
```

--------------------------------

### Force Test Failure for Non-Crashing Errors

Source: https://github.com/juliapluto/pluto.jl/blob/main/test/frontend/README.md

Introduces a test failure by logging a specific error message to the console. This is used to mark handled but problematic situations.

```javascript
console.error("PlutoError ...")
```

--------------------------------

### Modifying Variables Across Cells

Source: https://github.com/juliapluto/pluto.jl/wiki/⚡-Writing-and-running-code

Variables can only be assigned and modified in a single cell to maintain reactivity. Use `begin...end` or `let...end` blocks to group modifications, or rename variables to avoid conflicts.

```julia
"I have $(n_today) pets"
```

```julia
begin
    n_today = n_yesterday
    n_today += 3
    n_today *= 2
end
```

```julia
n_yesterday = 0
```
