# `map` Function
|
|
|
|
-> **Note:** This page is about Terraform 0.12 and later. For Terraform 0.11 and
|
|
earlier, see
|
|
[0.11 Configuration Language: Interpolation Syntax](../../configuration-0-11/interpolation.html).
|
|
|
|
The `map` function is no longer available. Prior to Terraform v0.12 it was
|
|
the only available syntax for writing a literal map inside an expression,
|
|
but Terraform v0.12 introduced a new first-class syntax.
|
|
|
|
To update an expression like `map("a", "b", "c", "d")`, write the following instead:
|
|
|
|
```
|
|
tomap({
|
|
a = "b"
|
|
c = "d"
|
|
})
|
|
```
|
|
|
|
The `{ ... }` braces construct an object value, and then the `tomap` function
|
|
then converts it to a map. For more information on the value types in the
|
|
Terraform language, see [Type Constraints](../types.html).
