Type Conversion:- > from to Numbers: "33" => 33 "33abc" => NaN true => 1; false => 0 > from to Boolean: 1 => true; 0 => false; NaN => false; "" => false; "hitesh" => true; >convert during operations =>if string is written first then convert all after it to string: "2" + 2 + 2 = 222 "1" + 2 = 12 =>if string comes after then the conversion occurs at last 2 + 2 + "2" = 42 1 + 1 + "2" + 2 + 1 = 2221 #use +operand to convert the operand to number

[@ambaradhikari7425]

The reason is that an equality check == and comparisons > < >= = 0 is true and (1) null > 0 is false. On the other hand, the equality check == for undefined and null is defined such that, without any conversions, they equal each other and don’t equal anything else. That’s why (2) null == 0 is false. null is treated in a special way by the Equals Operator (==). In a brief, it only coerces to undefined: null == null; // true null == undefined; // true Value such as false, '', '0', and [] are subject to numeric type coercion, all of them coerce to zero.

Thank you so much it is wonderful information

[@RahulKumar-ed9vw]

Thanks for information.👍👍

[@sameer07x19]

This explanation is neat 👍

[@anitaverma-p7i]

if consider null=0,then why is console.log(null==0)//false

[@SmoofyAESTHETE]

The equality (==) operator checks whether its two operands are equal, returning a Boolean result. Unlike the strict equality operator, it attempts to convert and compare operands that are of different types.

null is == 0 must be correct by that concept then but it is false

[@samadsiddiqui5925]

/*-----Comapring String and Number-------*/ console.log("2" > 5); //Output: false (Here, the string value is getting change into number and then it is getting compared with the given no. 5) /*-----Comapring String and Boolean-------*/ console.log("0" >= false); //Output: false (Here, the string value is getting change into number and then it is getting compared with the given boolean value false) /*-----Comapring Null and Number-------*/ console.log(null > 0); //Output: false (Here, > sign is changing the Null value into number i.e. 0 and 0 > 0 will give false) console.log(null == 0); //Output: false (Here, == can't change the Null because {>,=,= 0); //Output: true (Here, >= made the Null change into 0 and then 0 >= 0 so yeah that's true) /*-----Comapring Undefined and Number-------*/ console.log(undefined > 0); //Output: false console.log(undefined == 0); //Output: false console.log(undefined >= 0); //Output: false //All three outputs were false because undefined can't change into number in these situations.

[@ShahidIjaz-t3o]

as u said, in comparison operator made null as 0 in 2nd console null==0 means 0==0 why is false?

[@lizzimcguire4554]

The reason is that an equality check == and comparisons > < >= = 0 is true and (1) null > 0 is false. On the other hand, the equality check == for undefined and null is defined such that, without any conversions, they equal each other and don’t equal anything else. That’s why (2) null == 0 is false. null is treated in a special way by the Equals Operator (==).

New video kab ayga?...(JavaScript)

[@RajivRanjan-w6b]

(null == 0 ) --> here null is not converted , but in ( '2' ==2) --> converted and check , u said in equality check it is not converted but in '2' it is getting converted.

[@himanisain7738]

nice and helpful tutorial.

[@JitendraNathChandra]

But Sir the comparison between "2" and "j" console.log("2">"j") is false because of 2 unicode 50 and j unicode is 106 , since 2 comes before j that's why "2" is not greater than "j" right?

[@Abhisheksingh-nt8fv]

sir please typescript ka bhi tutorial hindi me in depth upload kijiye please

[@ankushladani496]

If null is treated as 0 then 2nd should also be give true. Why it's not?

[@TradingTales]

Same doubt

[@NaveenM-qz8dt]

Because equality check doesn't convert null into 0 only comparision operators do

[@muhammadumair72114]

please explain how console.log(null == 0) is false??? (*you said JS treats null as 0) where as console.log(null >= o) is true???

[@akshitagarg5914]

Why is null == 0 is false if null is converted to 0

[@abdulmatania8155]

Only comparisons convert null to 0, not equality operator.

[@ShubhamPanchal-zv7bp]

accha tu bada janta he@@abdulmatania8155

[@muhammadhassan48]

The answer to that is rather simple: a NULL means that there is no value, we're looking at a blank/empty cell, and 0 means the value itself is 0.

[@JRehmanRehman]

Sir phir yaha (2) me null == 0 iska result false q aaya hai jub null convert hojata hai 0 me🤔

[@1amAjay]

How sir doing copy console.log in next line, koi btaega 5:34

[@aiza671]

ctrl+ shift+ down arrow

[@aniketkadam9830]

If null is converted to zero, why does null == 0 return false?

[@navnisingh5512]

Bcz only comparisons let the js convert the data types... Not equality checks ( they treat null as null ,not 0)
