# @babel/plugin-transform-template-literals
> Compile ES2015 template literals to ES5
## Example
**In**
```javascript
`foo${bar}`;
```
**Out**
```javascript
"foo".concat(bar);
```
## Installation
```sh
npm install --save-dev @babel/plugin-transform-template-literals
```
## Usage
### Via `.babelrc` (Recommended)
**.babelrc**
Without options:
```json
{
"plugins": ["@babel/plugin-transform-template-literals"]
}
```
With options:
```json
{
"plugins": [
["@babel/plugin-transform-template-literals", {
"loose": true
}]
]
}
```
### Via CLI
```sh
babel --plugins @babel/plugin-transform-template-literals script.js
```
### Via Node API
```javascript
require("@babel/core").transform("code", {
plugins: ["@babel/plugin-transform-template-literals"]
});
```
## Options
### `loose`
`boolean`, defaults to `false`.
When `true`, tagged template literal objects aren't frozen. All template literal expressions and quasis are combined with the `+` operator instead of with `String.prototype.concat`.
When `false` or not set, all template literal expressions and quasis are combined with `String.prototype.concat`. It will handle cases with `Symbol.toPrimitive` correctly and throw correctly if template literal expression is a `Symbol()`. See [babel/babel#5791](https://github.com/babel/babel/pull/5791).
**In**
```javascript
`foo${bar}`;
```
**Out**
```javascript
"foo" + bar;
```
