|
| 3214 |

* If a `defaultValue` is provided, it'll use that over `string`,
|
| 3215 |

* if a value isn't found in provided language files.
|
| 3216 |
+
* This is useful if you want to have a descriptive key for token replacement

|

|

+
* {
|
| 3222 |
+
* "progress bar timing: currentTime={1} duration={2}": "{1} of {2}"
|
| 3223 |
+
* }
|
| 3224 |
+
* ```
|
| 3225 |
+
* It is then used like so:
|
| 3226 |
+
* ```js
|
| 3227 |
+
* this.localize('progress bar timing: currentTime={1} duration{2}',
|
| 3228 |
+
* [this.player_.currentTime(), this.player_.duration()],
|
| 3229 |
+
* '{1} of {2}');
|
| 3230 |
+
* ```
|
| 3231 |
+
*
|
| 3232 |
+
* Which outputs something like: `01:23 of 24:56`.
|
| 3233 |
+
*
|
| 3234 |
+
*
|
| 3235 |
+
* @param {string} string
|
| 3236 |
+
* The string to localize and the key to lookup in the language files.
|
| 3237 |
+
* @param {string[]} [tokens]
|
| 3238 |
+
* If the current item has token replacements, provide the tokens here.
|
| 3239 |
+
* @param {string} [defaultValue]
|
| 3240 |
+
* Defaults to `string`. Can be a default value to use for token replacement
|
| 3241 |
+
* if the lookup key is needed to be separate.
|
| 3242 |
+
*
|
| 3243 |
+
* @return {string}
|
| 3244 |
+
* The localized string or if no localization exists the english string.

* - Hidden elements have a width of 0 with `window.getComputedStyle`. This function

* defaults to the `Component`s `style.width` and falls back to `window.getComputedStyle`.
