### 学习书籍《用Go实现解释器和编译器》

---

### 语言特性

- 整型

- 布尔型

- 字符串

- 数组

- 哈希表

- 前缀、中缀、索引运算符

- 全局 | 局部变量绑定

- 表达式(1+1,1<1, 1!=1, 1==1...)

- return语句

- if语句

- 赋值

- 函数

- 高阶函数

- 内置函数 

- 简单宏实现

### 示例

- 变量绑定

```

let foo = "bar";

puts(foo); // bar

let a = 1;

a; // 1

let a = 1 < 2 && 2 > 1;

a; // true

let a = 1 < 2 || 2 > 1;

a; // true

```

- 数组

```

let arr = [1,2,3];

arr; // [1,2,3]

arr[0]; // 1 

```

- hash

```

let obj = {a:1};

obj; // {a:1};

obj["a"]; // 1

```

- if else

```

if(true){ 1 };

if(false){ 1 }else{ 2 };

if(1 < 2){ 1 }

if(1+1 > 1){ 2 }

if(1+1 >= 1){ 2 }

if(1+1 <= 1){ 2 }

let a = if(true){ 1 };

a; // 1

```

- function

```

let f = fn(x){ return 1;};

f(2); // 1

let a = 0;

a = 1;

puts(a); // 1

```

### TODO

- 赋值语句

```

let arr = [1,2,3];

arr[0] = 3;

arr[0]; // 3

let obj = {"a":1};

obj["a"] = 3;

obj["a"]; // 3

```

- 浮点数

```

let foo = 1.1;

puts(foo) //1.1

```
