How to access object property as a string in javascript [duplicate]

Question

I can do var foobar = foo.barto access the bar variable.

How would I do this if I had an arbitrary string that told me what element I needed to access. foo."bar" doesn't work.

Computed is so [], but the way you initially do is also using strings... and every property has a string as name. You can't say "access object property as a string" since it's always string, e.g., the first value at computed index [] casts into string too, so a[0] is a['0'] — user5066707

I think

foo["bar"]

is the syntax you need
