What is Hashicorp Terraform?
Terraform is developed by Hashicorp and the original author is Mitchell Hashimoto et al. The initial release date of terraform is 28 July 2014.
HashiCorp Terraform is an open-source infrastructure as code (configuring the infrastructure through code) tool that lets you define both cloud and on-prem resources in human-understandable configuration files that you can version, reuse, and share. You can use a consistent workflow to provision and manage all of your infrastructure all over its lifecycle.
Terraform consists of low-level components like compute, storage, and networking resources, as well as high-level components like DNS entries and SaaS features.
HashiCorp Terraform helps organizations enhance productivity, minimize risk, and enhance business speed as they integrate cloud into their IT environments.

Correction-Ansible follows Imperative(Procedural) Approach NOT Declarative.
‘Procedural style’ language implies you write code that specifies, step-by-step, how to achieve the desired end state. The onus is on the user to determine the optimal deployment process.
Terraform, SaltStack, and Puppet use a declarative style where you write code that specifies the desired end state. The IaC tool itself then determines how to achieve that state in the most efficient way possible.
Also, Config Mgmt tools like Ansible,Chef,Puppet provision components in a MUTABLE fashion.
An immutable infrastructure is one in which servers are never modified after they are deployed. If something needs to be updated or changed, new servers are built afresh from a common template with the desired changes. This is the world of Terraform, where new servers replace the existing servers. This is also the philosophy of ‘containers’.
Configuration management tools such as Chef, Puppet, and Ansible typically create a mutable infrastructure. For example, using Chef to install a new version of a software, it will run the software update on the existing servers and the changes will happen in-place.
Drawback of mutable:
Over time, as you apply more and more updates, each server builds up a unique history of changes. As a result, each server becomes slightly different than all the others, leading to subtle configuration bugs that are difficult to diagnose and reproduce (configuration drift). Even with automated tests, these bugs are difficult to catch; a configuration management change might work just fine on a test server, but that same change might behave differently on a production server because the production server has accumulated months of changes that are not reflected in the test environment.

hi,
“Ansible: It follows a declarative Infrastructure as a Code approach.”
Ansible is more imperative approach
