Handling unexpected side effect in computed properties - VueJS

Question

In the following code, I\'m trying to use the getTranslation object to map values present in originalKeys array and push the values in a new array

ESLint is showing this error because you are mutating the original data in computed property. It is recommended that you should return new references or data from computed property.Follow this link for detailed explanation. https://github.com/vuejs/eslint-plugin-vue/blob/master/docs/rules/no-side-effects-in-computed-properties.md
