php - symfony framework twig template script_controller principle solution

Question

I saw similar loading page js controller code (below) on the twig template of the framework

{% extends 'TopxiaWebBundle::layout.html.twig' %}
{% set script_controller = 'ldbundle/lds-micro/micro-course' %}

{% block title %} 报考专题{% endblock %}

I don’t know about it

script_controller = 'ldbundle/lds-micro/micro-course'

Which plug-in statement does

belong to? and his source code. Gods, please solve it! ! !

Answer 1

This makes no sense. . . It is set variable = value of twig template, which is assignment
