<\/span><\/h2>\nOne convenient way to find a key with a particular value in a Ruby hash is by using the find<\/code> method available in the Enumerable module. The find<\/code> method returns the first key-value pair for which the block condition is true.<\/p>\n“`ruby
\ndef find_key(hash, value)
\n hash.find { |key, val| val == value }&.first
\nend
\n“`<\/p>\n
How to find key with value Ruby?<\/strong><\/p>\nTo find a key with a particular value, you can use the find_key<\/code> method shown above, passing in the hash and the value you are looking for. The method will return the key associated with the specified value.<\/p>\n“`ruby
\nhash = { name: ‘John’, age: 30, occupation: ‘Developer’ }
\nvalue = ‘John’
\nkey = find_key(hash, value)
\nputs key # Output: name
\n“`<\/p>\n
Note:<\/strong> The use of the safe navigation operator &.<\/code> ensures that if no key-value pair matches the given value, the method returns nil<\/code> instead of raising an error.<\/p>\n
