The Ruby has_value? approach just checks to see if a hash has a details worth or otherwise. If it does, real will certainly be returned. If the worth is not discovered, incorrect will certainly be returned.

 some_hash = {"first_name" => > "David", "last_name" => > "Smith"}
places some_hash. has_value? "David".
#Output.
real.

The has_value? approach is rather simple yet can be actually valuable when searching for details saved in a hash.

Let’s take a look at some even more instances of the has_value? approach.

 some_hash = {"id" => > "1", "first_name" => > "David", "last_name" => > "Smith", "age" => > "45"}
places some_hash. has_value? "first_name".
places some_hash. has_value? "David".
places some_hash. has_value? "last_name".
places some_hash. has_value? "45".
places some_hash. has_value? 45.
#Output.
incorrect.
real.
incorrect.
real.
incorrect.

Let’s have a look at the has_key? approach in Ruby to obtain the various other worths in our hash.

Inspect If Trick Exists in Hash Making use of the Ruby has_key? Method

We took a look at the has_value? approach over to see if a specific worth was included in our hash. Currently we can utilize the has_key? approach to see if specific secrets are included in our hash.

 some_hash = {"first_name" => > "David", "last_name" => > "Smith"}
places some_hash. has_key? "first_name".
#Output.
real.

Let’s run the very same instances over, yet this moment look for specific secrets that could be included in the hash.

 some_hash = {"id" => > "1", "first_name" => > "David", "last_name" => > "Smith", "age" => > "45"}
places some_hash. has_key? "first_name".
places some_hash. has_key? "David".
places some_hash. has_key? "last_name".
places some_hash. has_key? "age".
places some_hash. has_key? "".
#Output.
real.
incorrect.
real.
real.
incorrect.

Hopefully this short article has served for you to discover just how to the Ruby has_value? approach functions.
