There are several ways to utilize v-model in VueJS while maintaining the value's immutability:
Use a computed property to create a copy of the value passed through v-model and bind the copy to the input field. This preserves the original value and creates a separate, mutable copy.
Use a watcher to listen for changes to the value passed through v-model and update a separate variable with the new value. This allows for the original value to remain immutable while still allowing changes to be made.
Use a deep clone method like lodash's cloneDeep to create a copy of the value passed through v-model before binding it to the input field. This ensures that the original value remains unchanged.
Use a custom component that handles the v-model binding and emits events for changes to the original value. This allows for control over how the value is mutated and prevents accidental changes to the original value.
