Sample from the book
(Below Questions and Answers are randomly taken from different pages of the book)
 
17: What is the difference in evaluating [“8”+5+2] and [8+5+”2”]?
Answer:
In [“8”+5+2],”8” is a String. So anything that trail the string will be changed to string. Hence the result will be”852”.
In [8+5+”2”], 8 and 5 are integer, so it gets added up (13).And “2” is treated as String. Hence the concatenation takes place and the result will be “132”.
 
18: Is it possible to assign a string to a floating point variable?
Answer:
Yes. Any variable can be assigned to another data type. For example,
var a1=10.39;
document.write(a1);10.39
a1=”hai”;
document.write(a1);hai
 
19: Will variable redeclaration affect the value of that variable?
Answer:
No. The same value will be retained in the variable.Example:
var status=”cool”;
document.write(“status”); //cool
var status;
document.write(“status”); //cool
status=”chill”;
document.write(“status”); //chill
 
20: How will you search a matching pattern globally in a string?
Answer:
A matching pattern can be globally searched in a string using “g” modifier in Regular Expression.
Example:
var p1=”First_Regular_ Expression_First”;
var q1=”/First/g”;
document.write(“Pattern_Match:” + p1.match(q1)); // Pattern_Match:First,First
