ObjectConstructor (interface)

interface ObjectConstructor {
  toPrimitive(
    input: any,
    hint: "string" | "number" | "default",
  ): string | number | bigint | boolean | undefined | symbol | null;
  isPrimitive(input: any): boolean;
}

ObjectConstructor.toPrimitive (method)

Convert the specified value to a primitive value.

The provided hint indicates a preferred return type, which may or may not be respected by the engine.

See the abstract operation "ToPrimitive" in the ECMAScript standard for more info.

toPrimitive(input: any, hint: "string" | "number" | "default"): string | number | bigint | boolean | undefined | symbol | null;

ObjectConstructor.isPrimitive (method)

Returns a boolean indicating whether the specified value is a primitive value.

isPrimitive(input: any): boolean;

StringConstructor (interface)

interface StringConstructor {
  cooked(
    strings: readonly string[] | ArrayLike<string>,
    ...substitutions: any[]
  ): string;
}

StringConstructor.cooked (method)

A no-op template literal tag.

cooked(strings: readonly string[] | ArrayLike<string>, ...substitutions: any[]): string;

BigIntConstructor.tdiv (method)

Return trunc(a/b).

b = 0 raises a RangeError exception.

tdiv(a: bigint, b: bigint): bigint;

BigIntConstructor.fdiv (method)

Return \lfloor a/b \rfloor.

b = 0 raises a RangeError exception.

fdiv(a: bigint, b: bigint): bigint;

BigIntConstructor.cdiv (method)

Return \lceil a/b \rceil.

b = 0 raises a RangeError exception.

cdiv(a: bigint, b: bigint): bigint;

BigIntConstructor.ediv (method)

Return sgn(b) \lfloor a/{|b|} \rfloor (Euclidian division).

b = 0 raises a RangeError exception.

ediv(a: bigint, b: bigint): bigint;

BigIntConstructor.tdivrem (method)

Perform trunc(a/b) and return an array of two elements. The first element is the quotient, the second is the remainder.

b = 0 raises a RangeError exception.

tdivrem(a: bigint, b: bigint): [bigint, bigint];

BigIntConstructor.fdivrem (method)

Perform \lfloor a/b \rfloor and return an array of two elements. The first element is the quotient, the second is the remainder.

b = 0 raises a RangeError exception.

fdivrem(a: bigint, b: bigint): [bigint, bigint];

BigIntConstructor.cdivrem (method)

Perform \lceil a/b \rceil and return an array of two elements. The first element is the quotient, the second is the remainder.

b = 0 raises a RangeError exception.

cdivrem(a: bigint, b: bigint): [bigint, bigint];

BigIntConstructor.edivrem (method)

Perform sgn(b) \lfloor a/{|b|} \rfloor (Euclidian division) and return an array of two elements. The first element is the quotient, the second is the remainder.

b = 0 raises a RangeError exception.

edivrem(a: bigint, b: bigint): [bigint, bigint];

BigIntConstructor.sqrt (method)

Return \lfloor \sqrt(a) \rfloor.

A RangeError exception is raised if a < 0.

sqrt(a: bigint): bigint;

BigIntConstructor.sqrtrem (method)

Return an array of two elements. The first element is \lfloor \sqrt{a} \rfloor. The second element is a-\lfloor \sqrt{a} \rfloor^2.

A RangeError exception is raised if a < 0.

sqrtrem(a: bigint): [bigint, bigint];

BigIntConstructor.floorLog2 (method)

Return -1 if a \leq 0 otherwise return \lfloor \log2(a) \rfloor.

floorLog2(a: bigint): bigint;

BigIntConstructor.ctz (method)

Return the number of trailing zeros in the two’s complement binary representation of a.

Return -1 if a=0.

ctz(a: bigint): bigint;
