Module value 

The value shape validates: what JSON can carry, plus the four things the canonical behaviour needs and JSON cannot say (an absent value, NaN, a date, a bigint), with object keys in insertion order.

Enums

Value

A value under validation, or produced by it.

Constants

ERR_VALUE_LIMIT

The limit a rendered value is clipped to in a message.

Functions

is_integer

Whether a number is an integer as Number.isInteger judges it.

js_date_string

A date as Date.prototype.toISOString prints it: UTC, millisecond precision.

js_number

A number as JavaScript’s Number.prototype.toString prints it: the shortest digits that read back as the same double, an integer without a point, an exponent below 1e-6 and from 1e21.

json_render

A value as JSON.stringify prints it after shape’s replacer: keys in insertion order, no spaces, NaN as the text NaN, an undefined element as null and an undefined property omitted, a date as its ISO text.

json_text

A string as JSON.stringify prints it, quotes included: no HTML escaping.

truncate_text

Clip a rendering to limit characters, the last three an ellipsis.

value_kind

The kind a message calls a value: “value” for nothing, null or NaN, otherwise its typeof, with arrays told from objects.

value_to_string

A value as a message names it: its JSON with the quotes stripped, clipped.

Type Aliases

Map

An object: keys in insertion order, as a JavaScript object keeps them.
