The RegExp object is used for matching text with a pattern.

Boolean values can be one of two values: true or false, representing the truth value of a logical proposition.

A unicode character class escape is a kind of character class escape that matches a set of characters specified by a Unicode property. It's only supported in Unicode-aware mode. When the v flag is enabled, it can also be used to match finite-length strings.

The glyph-orientation-horizontal attribute affects the amount that the current text position advances as each glyph is rendered.

The const declaration declares block-scoped local variables. The value of a constant can't be changed through reassignment using the assignment operator, but if a constant is an object, its properties can be added, updated, or removed.

The dx attribute indicates a shift along the x-axis on the position of an element or its content.

The let declaration declares re-assignable, block-scoped local variables, optionally initializing each to a value.

The intercept attribute defines the intercept of the linear function of color component transfers when the type attribute is set to linear.

The limitingConeAngle attribute represents the angle in degrees between the spot light axis (i.e., the axis between the light source and the point to which it is pointing at) and the spot light cone. So it defines a limiting cone which restricts the region where the light is projected. No light is projected outside the cone.
