What is the difference between '==' & '===' operators?

Answer 1

== equal to comparison
=== Identical(equal and of the same type)

Answer 2

== this check only value but === this check value and data type. Ex 2===2 same value and same data type but 2=="2" same value but not same data type.

Answer 3

Please use search bar before, to avoid dublicates... Hope these helps you.. Thank you..

Answer 4

"1" == 1 is true. But
"1" === 1 is false.

Answer 5

== is used for comparison between two variables irrespective of the datatype of variable. === is used for comparision between two variables but this will check strict type, which means it will check datatype and compare two values.

Answer 6

== is used to conpare two values
=== is used to compare two values and their type

Answer 9

== only compares the values but === compares values and types
For example:
$a = 1;
$b = "1";

$a == $b ; returns TRUE because the both have the same value that is 1

$a === $b; returns FALSE because the value of $b wrote in double quotation " " and it's defined as string type while the $a value has not quotation and defined as integer
So and integer is not same as string type and it returns false

Answer 10

If the comparison is between the same value type both == and === do exactly the same thing. If the value types being compared are different the == differs from === in that it allows type conversion before the comparison.By default the non-number values ("5",true,false) to be converted to numbers (5,1,0) before the comparisons are made. For more details see https://github.com/Li-YangZhong/You-Dont-Know-JS/blob/2nd-ed/get-started/ch2.md here

Answer 11

== compares only the value.
=== compares value and type.

e.g. 5 == "5" is true.
5 === "5" is not true.

Answer 12

== checks two variables same or not, it doesn't check the data type.
=== checks two variables same or not and the data type must have to be same.

"1" == 1 it will return true. Here the 1st 1 is string and the 2nd 1 is integer. It is true because the values are same.

"1" === 1 it will return false. Though the values are same but the data types doesn't match.

Answer 13

'==' denote equal to
For example :
10==10; its true
And
'===' its identically equal to and same
For example
10===10

Answer 15

Sorry

No need to be sorry. Don't say that.. Its just information and a request giving to you.. Because dublicates may gets deleted by mods to keep search bar, & SL clean..
So information only..

Answer 17

== only checks the content if they match. Like string "1" & integer 1. It will return true because content is same though data types are not same.

But === also checks if they are of same data type,which in above case is not true, as "1" is string & 1 is number. So that will return false now.

Answer 18

JavaScript has an incredibly weird typesystem. To fix this, == will check if they are the same regardless of type whilst === will check the type. Examples:
‘0’ == 0 // True
‘0’ === 0 // False
0 == 0 // True
0 === 0 //True.

I do not know much about JS other than the bare basics, but I’d imagine that you should use === instead of == most of the time.

Answer 19

double equal is for compare

'5' == 5 --> true

three equal is identical
'5' === 5 --> false

Show '5' is a string, but 5 is int.
