Are there any methods which work exactly like []= but return the changed
array, different from []= which returns void?

Array#fill?
a = [0, 1, 2, 3]
=> [0, 1, 2, 3]
irb(main):006:0> a.fill("x", 2..2)
=> [0, 1, "x", 3]

irb(main):008:0> a='abc'
=> "abc"
irb(main):009:0> a[1]=?a
=> 97
irb(main):013:0> a[1..1]="a"
=> "a"
thus String#= is behaving differently from Array#=

Sorry, what I meant was :
a = "abc"
=> "abc"
a (some method with arguments of 1 and "d")
=> "adc"
I wanted to find out are there any methods behaving like this.

a = "abc"
a[1,1] = "d"
a # => "adc"
a[1] = ?b
a # => "abc"

Yes #=, what is wrong with it? Would you prefer a method with a
different name, I am not sure there is one.

None directly that I know of, but ...
a = "abc
a.split('').fill("d",1,1).join
or
(a[1]='d';a)

a = "abc"
p a[1] = "d" # I think the OP wants to see "adc" here
p a # not just here
