String.prototype.bold()

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The bold() method creates a string that embeds a string in a <b> element (<b>str</b>), which causes a string to be displayed as bold.

Note: All HTML wrapper methods are deprecated and only standardized for compatibility purposes. Use DOM APIs such as document.createElement() instead.
