Sir I just wanted to ask that, for web developer position whether we should learn DSA by solving questions in javascript OR we should solve questions in C++, Java .which one is better ?

@yogendraprabhakar6834 Год назад

It really depends, If you are targeting product-based firms then you should focus more on DSA regardless of any programming language. But if you just want to get a job instantly in any service or startup firms, then you should more into development, you should be able to build projects. As a fresher you should aware of logical and apptitude as well.

Let and Const are also hoisted, but they are in temporal deadzone, therefore reference error.

Q1) why is it undefined? When the variable value is "apple"

@subhu143 Год назад

Because we use that variable before we declare that, that variable was declared using var that's why give undefined if that declared using let or const then the output should be error this is called hoisting in javascript

@kavita3316 Год назад

It's because of hoisting. Read more about it in Namaste JS.
