for those who are still confused in =,==,=== operaters

Question

=(equal) is used for assigning a value to variable,
 == operator will compare for equality after doing any necessary type conversions. The === operator will not do the conversion, so if two values are not the same type === will simply return false. It's this case where === will be faster, and may return a different result than ==. In all other cases performance will be the same.

Example:
20 == '20' , will return TRUE
20 === '20' , will return FALSE

Answer 1

= for assigning a value to a variable
like var age = 20;
== for comparing two variables whether they are of equal type
=== for comparing two variables whether they are strictly equal

sample code:
var age1= 20; //age1 is just a variable not object
var age2 = new number(20); /* age2 is an object here as we used number constructor function using the keyword new */
alert(age1 == age2); // true
alert(age1 === age2); //false

hope this helps you

Answer 2

example for ==
var a = "42"; // string
var b = 42; // number
if(a == b) // true
in case of == the comparison is made between two values after the necessary conversion of values of either side from one data type to another. like in the above example ist a is converted into NUMBER from STRING data type and then the comparison occurs and result is true.
but if we have used ===. operator then the result would have been false
because this operator won't let convert the values of either side their data type.

if(a===b) // false

Answer 3

== used to compare values, === used to compare both value and datatype

Answer 4

Honestly, I'd still be confused after reading this.

Answer 5

= is use to denote values like x =5 , now x will have value 5

Answer 6

== is usually use to compare value on certain conditions like in IF and FOR loop ...

Answer 7

What is java

Answer 8

I understood the movie inception
but ,
not this

Answer 9

@Codde Ded because age2 is an object whereas age1 is a number

Answer 10

`=` Assign value.
`==` Check if the same value.
`===` Check if the same value and data type.

Answer 11

= for assigning a value to a variable
like var age = 20;
== for comparing two variables whether they are of equal type
=== for comparing two variables whether they are strictly equal

sample code:
var age1= 20; //age1 is just a variable not object
var age2 = new number(20); /* age2 is an object here as we used number constructor function using the keyword new */
alert(age1 == age2); // true
alert(age1 === age2); //false

Answer 12

Define please the terms object and type?

Answer 13

me

Answer 14

@Kandula Samantha, but why is this so?
I would assume age1 and age2 are of the same value types: integers. why would '===' then evaluate to 'false'?

what is the javascript engine comparing here: values against values, or values against value types?

Answer 15

still confused

Answer 16

like if u r studying in 2017
