Those who want to give mock tests can mail on practicemocks223@gmail.com I have given around 100+ interviews(30+ uploaded) and accordingly your interview will be taken. Feedback will be given one on one in the way you can give better interviews in the near future.
No, its correct - it will print 'hello' in this case. But if we use like this 'console.log(a); a = hello;' it will throw an error as 'a' is undefined. Because JavaScript is dynamically typed language - 'var' or 'let' or 'const' are not required - without using this, we can declare a variable with some values.
