You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: masgn.rb
    path of file: ./repos/opal/lib/opal/nodes
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'opal/nodes/ba
    
      def compile_masgn(lhs_items, array, len = nil)
        pre_splat  = lhs_items.take_while { |child| child.type != :splat }
        post_splat = lhs_items.drop(pre_splat.size)

        pre_splat.each_with_index do |child, idx|
          compile_assignment(child, array, idx, len)
        end

        unless post_splat.empty?
          splat = post_splat.shift

          if post_splat.empty? # trailing splat
            if part = splat.children[0]
              helper :slice
              part = part.dup << s(:js_tmp, "$slice(#{array}, #{pre_splat.size})")
              push ', '
              push expr(part)
            end
