Returns the lowerCamelCase form of a string.

'innerHTML'.camelize();          // 'innerHTML'
'action_name'.camelize();        // 'actionName'
'css-class-name'.camelize();     // 'cssClassName'
'my favorite items'.camelize();  // 'myFavoriteItems'
'My Favorite Items'.camelize();  // 'myFavoriteItems'

Returns the Capitalized form of a string

'innerHTML'.capitalize()         // 'InnerHTML'
'action_name'.capitalize()       // 'Action_name'
'css-class-name'.capitalize()    // 'Css-class-name'
'my favorite items'.capitalize() // 'My favorite items'

Returns the UpperCamelCase form of a string.

'innerHTML'.classify();          // 'InnerHTML'
'action_name'.classify();        // 'ActionName'
'css-class-name'.classify();     // 'CssClassName'
'my favorite items'.classify();  // 'MyFavoriteItems'

Replaces underscores, spaces, or camelCase with dashes.

'innerHTML'.dasherize();          // 'inner-html'
'action_name'.dasherize();        // 'action-name'
'css-class-name'.dasherize();     // 'css-class-name'
'my favorite items'.dasherize();  // 'my-favorite-items'

Converts a camelized string into all lower case separated by underscores.

'innerHTML'.decamelize();           // 'inner_html'
'action_name'.decamelize();        // 'action_name'
'css-class-name'.decamelize();     // 'css-class-name'
'my favorite items'.decamelize();  // 'my favorite items'

Apply formatting options to the string. This will look for occurrences of "%@" in your string and substitute them with the arguments you pass into this method. If you want to control the specific order of replacement, you can add a number after the key as well to indicate which argument you want to insert.

Ordered insertions are most useful when building loc strings where values you need to insert may appear in different orders.

"Hello %@ %@".fmt('John', 'Doe');     // "Hello John Doe"
"Hello %@2, %@1".fmt('John', 'Doe');  // "Hello Doe, John"

Mark a string as safe for unescaped output with Handlebars. If you return HTML from a Handlebars helper, use this function to ensure Handlebars does not escape the HTML.

Ember.String.htmlSafe('<div>someString</div>')

Formats the passed string, but first looks up the string in the localized strings hash. This is a convenient way to localize text. See Ember.String.fmt() for more information on formatting.

Note that it is traditional but not required to prefix localized string keys with an underscore or other character so you can easily identify localized strings.

Ember.STRINGS = {
  '_Hello World': 'Bonjour le monde',
  '_Hello %@ %@': 'Bonjour %@ %@'
};

Ember.String.loc("_Hello World");  // 'Bonjour le monde';
Ember.String.loc("_Hello %@ %@", ["John", "Smith"]);  // "Bonjour John Smith";

More general than decamelize. Returns the lower_case_and_underscored form of a string.

'innerHTML'.underscore();          // 'inner_html'
'action_name'.underscore();        // 'action_name'
'css-class-name'.underscore();     // 'css_class_name'
'my favorite items'.underscore();  // 'my_favorite_items'

Splits a string into separate units separated by spaces, eliminating any empty strings in the process. This is a convenience method for split that is mostly useful when applied to the String.prototype.

Ember.String.w("alpha beta gamma").forEach(function(key) {
  console.log(key);
});

// > alpha
// > beta
// > gamma
