javascript - 标识符已声明 - 标识符 'userScore' 已被声明

对 JS 非常陌生，正在尝试创建剪刀石头布游戏。我只是从 JS 方面开始，在声明 const 时在第 1 行遇到错误。

我已经看到这是否是 userScore 和 userScore_Span 冲突的问题通过删除后者。另外，如果我删除第 1 行，那么第 2 行会出现相同的错误。

标识符“userScore”已经声明

//Initialising the variables
const userScore = 0;
const computerScore = 0;
const userScore_span = document.getElementById("user-score");
const computerScore_span = document.getElementById("comp-score");
const scoreBoard_div = document.querySelector(".score-board");
const result_div = document.querySelector(".result");
const rock_div = document.getElementById("r");
const paper_div = document.getElementById("p");
const scissors_div = document.getElementById("s");

//This is the entire js file
