# let: giving a value a name

[Syntax and values](README.md)

```text
let name = "Ada"
let score = 0
let finished = false
```

`let` declares one new name in the current lexical scope. The initializer is
evaluated before the name becomes visible, so a declaration cannot refer to
itself:

```text
let score = score + 1  # invalid unless an outer score is visible
```

There is no declaration without an initializer and no type-annotation syntax.

## Example

```pliro
# language: en
let score = 10
let bonus = score + 5
say score, bonus
```
