Displaying an array within a method using Vue.js

Question

Displaying an array within a method using Vue.js

As a complete newcomer to Vue, I wanted to experiment with methods a bit. Specifically, I attempted to print out an array of strings using the following method:

printStringArray(objectWithArray) {
      i = 0;
      s = '';

      while(i < objectWithArray.stringArray.length) {
        s = objectWithArray.stringArray[i] + s,
      }; 
      return  s;
    },

However, I encountered errors related to variables i and s. Despite attempting different approaches, I consistently received messages stating that either the variables were not defined or that although they were defined, they were not utilized. Have others faced this issue as well? Although I referenced working code snippets from other sources in order to identify my mistakes, I continued to encounter similar errors. It seems like a simple problem, but unfortunately, I haven't been able to locate any helpful resources on the topic.

Answer №1

Below is a simple method that can be used:

let numbers = [1, 2, 3, 4];
function displayArray(numbers){
    numbers.forEach(item => console.log(item))
}

displayArray(numbers);

Alternatively, the same result can be achieved with a while loop:

let num = [1, 2, 3, 4]
function showArrayElement(num){
    let index = 0;
    while (index < num.length){
        console.log(num[index]);
        index +=1;
    }
}

showArrayElement(num);

The focus here is more on the use of JavaScript rather than Vue. Let's get straight to the point:

If you want a function to convert an array to a string, you can simply use the toString method. Check out this example:

const items = [0, 1, "Apple", "Mango"];
const str = items.toString();
console.log(str);

One option is to utilize the join function to display the items with a space in between:

displayStringArray(data) {
      let joined = data.join(" ");
      console.log(joined)
     return joined;
    },
