## Definition 
The **`decodeURI()` function** is used to decode a URI by replacing escape sequences with their respective special characters. An example of an escape sequence is `%20`, which is replaced by the *space* character when `decodeURI` is applied. 

## Parameters
`decodeURI()` takes an encoded URI string as input. To get accurate results, this should be a string that was first encoded using the `encodeURI` function.

## Syntax 

#     
## Return value
`decodeURI()` returns the decoded URI. 

## Example


uri_example_one = "https://www.google.com/search?q=decodeuri%20example%20%C3%A5%D0%B5%D0%BB"
console.log( decodeURI(uri_example_one) )

uri_example_two = "https://www.educative.io/learning%20t%C5%8D%20d%C4%97c%C5%8Dd%C4%97"
console.log( decodeURI(uri_example_two) )

#     
## How to avoid exceptions 
`decodeURI` may throw an exception if the input string contains any invalid characters. Therefore, we advise using the function below inside a try-catch block: 


try {
  var encoded_uri = "%20"
  var decoded_uri = decodeURI(encoded_uri)
} catch(exception) {
  console.log(exception);
}

try {
  var encoded_uri = "%E"
  var decoded_uri = decodeURI(encoded_uri)
} catch(exception) {
  console.log(exception);
}

#      
## Usage 
`decodeURI` is used to decode complete URIs that have been encoded using `encodeURI`. Another similar function is `decodeURIComponent`. The difference is that the `decodeURIComponent` is used to decode a part of the URI and not the complete URI. 

If given the same *complete* URI encoded using `encodeURI`, the output would be the same for both functions because the same escape characters would be replaced in both. 

However, if we want to decode a URI that was encoded using `encodeURIComponent`, then the correct function to use would be `decodeURIComponent`.

## Examples

uri = "https://www.educative.io/learning tō dėcōdė"

encoded_complete_uri = encodeURI(uri)
decode_uri = decodeURI(encoded_complete_uri)
decode_uri_component = decodeURIComponent(encoded_complete_uri)

console.log("Complete uri being used: ", uri)
console.log("decodeURI: ", decode_uri )
console.log("decodeURIComponent: ", decode_uri_component)

uri = "query=?/learning tō dėcōdė"

encoded_complete_uri = encodeURIComponent(uri)
decode_uri = decodeURI(encoded_complete_uri)
decode_uri_component = decodeURIComponent(encoded_complete_uri)

console.log("Part of the uri being used: ", uri)
console.log("decodeURI: ", decode_uri )
console.log("decodeURIComponent: ", decode_uri_component)

What is decodeURI() in JavaScript?

decodeURI() decodes encoded URIs in JavaScript by replacing escape sequences with their respective characters.
