typescript - TSLint: for statements must be braced (curly)

Question

I want to use this code to generate String.

randomString(): string {
    const length = 40;
    const chars = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
    let result = '';
    for (let i = length; i > 0; --i) result += chars[Math.floor(Math.random() * chars.length)];
    return result;
  }

But I get this error:

TSLint: for statements must be braced (curly)

Do you know in typescript what braces should I use?

Answer 1

for (let i = length; i > 0; --i) result += chars[Math.floor(Math.random() * chars.length)];

应该

for (let i = length; i > 0; --i) {
  result += chars[Math.floor(Math.random() * chars.length)];
}

您的 IDE 应该建议您自动解决此问题。
