how to pass a array of values to the template in the yeoman generator

[helxsz]

I am using yeoman-generator, which I need to pass a array of value to the template file. for example I want to pass a array of text values to the template.

  install() {
      async app() {
         let array = ['abc','cde','efg'];
           this.fs.copyTpl(
            this.templatePath('base','/abc.ts'),
            this.destinationPath('example/abc.ts'),
            {'array':array}
          );         
      } // app 
  }// install 

in the .ts file, i define a variable which received the passed array.

public options = <%= array %> ; My expected result is

public options = ['abc','cde','efg'] ; however the resulted output is

public options = abc,cde,efg ;how would I resolve this problem ?

public options = [<%= array.map(value => `'${value}'`).join(',') %>] ;
