The JavaScript exception "character class escape cannot be used in class range in regular expression" occurs when a Unicode-aware regular expression pattern contains a character class where a boundary of a character range is another character class, such as a character class escape.

The JavaScript exception "BigInt negative exponent" occurs when a BigInt is raised to the power of a negative BigInt value.

The tabindex attribute allows you to control whether an element is focusable and to define the relative order of the element for the purposes of sequential focus navigation.

The JavaScript exception "redeclaration of formal parameter" occurs when the same variable name occurs as a function parameter and is then redeclared using a let assignment in a function body again.

The width attribute defines the horizontal length of an element in the user coordinate system.

The writing-mode attribute specifies whether the initial inline-progression-direction for a <text> element shall be left-to-right, right-to-left, or top-to-bottom. The writing-mode attribute applies only to <text> elements; the attribute is ignored for <tspan>, <tref>, and <textPath> sub-elements. (Note that the inline-progression-direction can change within a <text> element due to the Unicode bidirectional algorithm and properties direction and unicode-bidi.)

The unicode attribute specifies one or more Unicode characters indicating the sequence of Unicode characters which corresponds to a glyph.

The word-spacing attribute specifies spacing behavior between words.
