What are nesting templates

The nesting template is a feature supported within template literals syntax to allow inner backticks inside a placeholder ${ } within the template. For example, the below nesting template is used to display the icons based on user permissions whereas outer template checks for platform type,

const iconStyles = `icon ${
isMobilePlatform()
? “”
: `icon-${user.isAuthorized ? “submit” : “disabled”}`
}`;
You can write the above use case without nesting template features as well. However, the nesting template feature is more compact and readable.

//Without nesting templates
const iconStyles = `icon ${
isMobilePlatform()
? “”
: user.isAuthorized
? “icon-submit”
: “icon-disabled”
}`;
