How to convert a normal string to a uppercase string using filter in VueJS ? Last Updated : 15 Dec, 2021 Comments Improve Suggest changes Like Article Like Report Filters are a functionality provided by Vue components that let you apply formatting and transformations to any part of your template dynamic data. The filter property of the component is an object. A single filter is a function that accepts a value and returns another value. The returned value is the one that’s actually printed in the Vue.js template. To uppercase string using filters, we have to write logic to convert a regular string into all uppercase and apply the filter on a required string.
