What are the types of formatting?

Basically there are 4 types of formatting available in i18n plugin,

1. Named formatting: First You need to define the message keys in curly braces({})

const messages = {
en: {
message: {
greeting: '{msg} Morning'
}
}
}

After that pass argument value along with key in the template

It outputs the result as below,

2. List formatting: First you need to define zero index based keys in the messages,

const messages = {
en: {
message: {
greeting: '{0} Morning'
}
}
}

After that pass argument value with in an array

Finally it outputs the result as below,

Note: It also accepts array-like object

3. HTML formatting: This formatting is required when want to render your translation as an HTML message and not a static string.

const messages = {
en: {
message: {
greeting: 'Good 
 Morning'
}
}
}
