What is the technical name for the double curly braces { } in react?
I think you're looking for the word 'interpolation'.
In Javascript, string interpolation is the evaluation of a string literal containing placeholders that are replaced with corresponding values during runtime.
curly braces - { } - can be two things:
- the definition of a Javascript object
- a way to "inject variables" in your HTML template
In react, since - { } - can be used to inject variables, double curly braces - {{ }} - are used to inject javascript objects within your JSX.
