Code blocks

Put ``` on the lines before and after a block of code.

For several lines of code, put three backticks on a line before and after it. Nothing inside is formatted, and spacing is kept exactly.

```
function greet(name) {
  return `Hello, ${name}!`;
}
```

function greet(name) {
  return `Hello, ${name}!`;
}

Name the language after the opening backticks. Apps that color code use it, and it tells readers what they're looking at.

```python
for item in basket:
    print(item)
```

for item in basket:
    print(item)

• Common names: js, ts, python, csharp, java, json, html, css, sql, bash, powershell, yaml.
• Three tildes (~~~) work in place of backticks. That's handy when the code itself contains ```.
• Lines indented by four spaces are also a code block. Fences are clearer, so prefer those.
