# `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).

~> **This function is deprecated.** From Terraform v0.12, the Terraform
language has built-in syntax for creating maps using the `{` and `}`
delimiters. Use the built-in syntax instead. The `map` function will be
removed in a future version of Terraform.

`map` takes an even number of arguments and returns a map whose elements
are constructed from consecutive pairs of arguments.

## Examples

```
> map("a", "b", "c", "d")
{
  "a" = "b"
  "c" = "d"
]
```

Do not use the above form in Terraform v0.12 or above. Instead, use the
built-in map construction syntax, which achieves the same result:

```
> {"a" = "b", "c" = "d"}
{
  "a" = "b"
  "c" = "d"
]
```
