Assume I have an object: var obj = { foo:"bar", fizz:"buzz" }; I need to access a property of that object dynamically like so: var objSetter = function (prop,val) { obj [prop] = val; } No problems there, except for that prop needs to be case insensitive in case the property name is passed into the function as, say, Foo instead of foo. The reason for that was given in SPARK-15229 ticket. How to ignore case sensitive when searching a key in the java.util.Map? array_change_key_case (PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8) array_change_key_case — Changes the case of all keys in an array Specifying this parameter when using Sort-Object indicates that the sort should be case sensitive.

Note that CaseInsensitiveMap is not synchronized and is not thread-safe. These are the top rated real world Python examples of requestsstructures.CaseInsensitiveDict.items extracted from open source projects. You can use array_change_key_case() to convert all cases to lower, and check on the lowercase key in array_key_exists().array_change_key_case() changes all keys to lowercase by default (but you can also change them to uppercase, by supplying the CASE_UPPER to the second argument - CASE_LOWER is default). 0. The pattern is used to do pattern-matching "search-and-replace" functions on text. RegExp Object. A JavaScript class is a type of function. The example below demonstrates how to make an unordered map with a string key case insensitive. The default is set to the parent DataSet object's CaseSensitive property, or false if the DataTable was created independently of a DataSet.

JSON allows to have same key name but with different case. LinkedHashMap variant that stores String keys in a case-insensitive manner, for example for key-based access in a results table.
