Local Storage

• the advantages of local storage/ the Needs that should be exsist to store:
  • a lot of storage space
  • on the client
  • that persists beyond a page refresh
  • and isn’t transmitted to the server
• HTML5 Storage is based on named key/value pairs.
• The named key is a string.

• he data can be any type supported by JavaScript, including strings, Booleans, integers, or floats. BUT the data is actually stored as a string.

• We can write this code :
  var foo = localStorage.getItem(“bar”); // … localStorage.setItem(“bar”, foo); …could be rewritten to use square bracket syntax instead:

var foo = localStorage[“bar”]; // … localStorage[“bar”] = foo;

• The localStorage property is read-only.

• Syntax for SAVING data to localStorage : localStorage.setItem(“key”, “value”);

• Syntax for READING data from localStorage: var lastname = localStorage.getItem(“key”);

• Syntax for REMOVING data from localStorage:localStorage.removeItem(“key”);
