Multiply numeric property values by 2
importance: 3
Create a function multiplyNumeric(obj)
that multiplies all numeric property values of obj
by 2
.
For instance:
// before the call
let
menu =
{
width
:
200
,
height
:
300
,
title
:
"My menu"
}
;
multiplyNumeric
(
menu)
;
// after the call
menu =
{
width
:
400
,
height
:
600
,
title
:
"My menu"
}
;
Please note that multiplyNumeric
does not need to return anything. It should modify the object in-place.
P.S. Use typeof
to check for a number here.
function
multiplyNumeric
(
obj
)
{
for
(
let
key in
obj)
{
if
(
typeof
obj[
key]
==
'number'
)
{
obj[
key]
*=
2
;
}
}
}
