Vue3 can't assign parameter-CodePudding

I want to make a function, where I am giving in 2 parameters, string, and array, and that array is equal to what I get from Axios, but I run into the problem {'assignment' is assigned a value but never used.}, but I want that the this.quizzAllCategories is equal to parameter assignment

callAPI(params: string, assignment: quizzType[]) {
      axios
        .get(`https://printful.com/test-quiz.php?action=${params}`)
        .then((res) => {
          assignment = res.data;
        });
    },
  },
  async created() {
    await this.callAPI("quizzes", this.quizzAllCategories);
  },

CodePudding user response：

You have to return the data from the function, not expect the "return variable" as another parameter, that's not how it works.

callAPI(params: string) {
  return axios
    .get(`https://printful.com/test-quiz.php?action=${params}`)
    .then((res) => {
      return res.data;
    });
  },
},
async created() {
  this.quizzAllCategories = await this.callAPI("quizzes");
},

ESLint lint behavior is right. You've declared assignment and assigned it a value, but u aren't using it in your Code anywhere.

Solution: It should disappear if use it anywhere:)

Solution 2 which is not recommended: you can disable it by adding these, before this line

// eslint-disable-next-line no-unused-vars

assignment = res.data

/* eslint-enable no-unused-vars */
