Why doesn't for work in ejs?

Question

Node.js

SyntaxError: Unexpected token 'for' in /var/www/html/app/views/index.ejs while compiling ejs

Writes this error if I try to for in an object
The code itself

<p><%= for(var i in table){
  i
} %></p>

The object I get is like this, I want to turn to the suburban one (and other elements at this level, if any)

{
  'Загородное': {
    'Администрация': [
      [pnd_1], [pnd_1], [pnd_1],
      [pnd_1], [pnd_1], [pnd_1],
      [pnd_1], [pnd_1], [pnd_1],
      [pnd_1], [pnd_1], [pnd_1],
      [pnd_1], [pnd_1], [pnd_1],
      [pnd_1], [pnd_1], [pnd_1],
      [pnd_1]
    ]
  }
}

Answer 1

Sign = before for is superfluous
