How To Use Custom Labels In Salesforce
Custom labels are custom text values, which can be called from apex classes, visual force pages or lightning components.
To support multilingual feature in an application, we can use custom labels that offer user’s to change/translate text values into any language that supported by salesforce.
It helps to provide the best user experience that offers application in the user’s native language.
