There are some steps to create String Interpolation Binding.

Step1) Suppose You create a component through below component

ng g c string-interpolation-binding

After run this command 4 files are created and one module file is updated.

CREATE src/app/string-interpolation-binding/string-interpolation-binding.component.html (43 bytes)
CREATE src/app/string-interpolation-binding/string-interpolation-binding.component.spec.ts (768 bytes)
CREATE src/app/string-interpolation-binding/string-interpolation-binding.component.ts (362 bytes)     
CREATE src/app/string-interpolation-binding/string-interpolation-binding.component.scss (0 bytes)     
UPDATE src/app/app.module.ts (1251 bytes)
