Answer 1

Answer:

a==5 is used in computer language but... a=5 is used by us.... (both have same value)

Answer 2

Answer:

a=5 this format is only used when you have to declare variables.

and

a==5 is used in if else statements and so on...

a==5 means a is equal to five then it can be string or integer data type but if there's a===5 then it means a is equal to five and they both lies in same data type.

eg.

a is equal to 5 ( in int) is defined but if you put

if(a == '5'){ return a}

then it will give true

but

if you put

if(a=== '5'){ return a}

this time it will give false because a is defined as 5 but it was in integer data but now you are checking it in string data type

so,

overall == is used to check values only whereas, === is used to same data types also.

Hope it helps...
