+==== HashMap ====
+Like dictionaries these use key value pairs.
+To make one
+<code rust>
+let mut name_and_age = HashMap::new();
+name_and_age.insert("Gassica",22);
+name_and_age.insert("Alex",12);
+name_and_age.get("Alex") //ACCESSING THE VALUE
+</code>
+You can also insert "entry"
+<code rust>
+name_and_age.entry(String::from("thomas")).or_insert(20); //Insert only if unique
+</code>
+which is bascially insert if unique. The aims to finish this by may atleast. (given I spend only a little time a week on it) will prollly do some exercizes thru the week without typing my noon-sense.((but typing this is fun fun fun fun)).
