Ukázka použití zpětných uvozovek

`Pomoci zpětné uvozovky vytvoříte speciální řetězec, který lze psát na více 
 řádků a dají se do něj vkládat výrazy ${ 1+2 }, proměnné ${ x+y }, pole ${ seznam[0] },
 objekty ${ uzivatelske.jmeno } a dokonce ihned volané funkce ${ function() { return x+y; }() } 
 nebo metody ${ "sidon".toUpperCase() }.`

Hello, I can work on your Angular projects. I have already worked on angular and developed some merchandizing, ecommerce and educational web apps and also dashboards. I can work on different angular versions from Angularjs to Angular11.
I am also fullstack developer, if you will have anything from backend then it will be of no problem. just leave me a message and i will get back to you.
thank you.
