Hi guys, I am working on cypress but wanted to know do we need to be expert in js to use the tool efficiently

It all depends on what meaning you put into the words "expert" and "efficiently") As I see it, you don't have to be a profi in JS to use Cypress, but knowing some JS can be helpful. Cypress has an easy-to-use interface, clear and concise documentation that is easy to follow, so people with different levels of programming experience can use it. Nevertheless, having good knowledge of JS can be helpful when using Cypress to make the most out of it.

I am learning all the coding methodologies of JS just wanted to know that's all , thank you

I wouldn't say you need to be an expert in JS, but it will require a significant amount of knowledge. Documentation and Good educators are really helpful, here are some resources: @nutritious-restaurant-91514 - https://filiphric.com/blog @acceptable-hamburger-48790 - https://medium.com/@gurudatt.sa26 @careful-insurance-62240 - https://qaautomationlabs.com/blogs/ Cypress Docs - https://docs.cypress.io/guides/overview/why-cypress

You can start using Cypress with little JS knowledge and inprove as you go. This was my path personally and worked for me

Which concepts of js should I mostly focus on?
