多次运行go测试时，crypto / rand产生相同的结果

Question

在使用中，加密货币/兰特在密码学上是安全的。那么，当我多次对同一代码进行go测试时，为什么会生成相同的结果呢？

相关代码：

const regex = /<\/[a-z]+>(?:\s+)<[a-z]+>/gm;
const str = `<p>leave white spaces</p>   <p>leave white spaces</p>    <p>leave white spaces</p>   <p>leave white spaces</p><p>leave white spaces</p>   <p>leave white spaces</p>    <p>leave white spaces</p>   <p>leave white spaces</p>
<p>leave white spaces</p>   <p>leave white spaces</p>    <p>leave white spaces</p>   <p>leave white spaces</p><p>leave white spaces</p>   <p>leave white spaces</p>    <p>leave white spaces</p>   <p>leave white spaces</p>
<p>leave white spaces</p>   <p>leave white spaces</p>    <p>leave white spaces</p>   <p>leave white spaces</p><p>leave white spaces</p>   <p>leave white spaces</p>    <p>leave white spaces</p>   <p>leave white spaces</p>

`;
const subst = ``;

// The substituted value will be contained in the result variable
const result = str.replace(regex, subst);

console.log(result);
