Buffer

The ArrayBuffer with which to share memory.

The octets to store.

The octets to store.

The buffer to copy.

count of octets to allocate.

encoding to use, optional. Default is 'utf8'

String to store in buffer.

If not specified, length of the this object is used as its default value.

If start is negative, it is treated as length+start. If end is negative, it is treated as length+end.

If target is negative, it is treated as length+target where length is the length of the array.

A function that accepts up to three arguments. The every method calls the predicate function for each element in the array until the predicate returns a value which is coercible to the Boolean value false, or until the end of the array.

An object to which the this keyword can refer in the predicate function. If thisArg is omitted, undefined is used as the this value.

index to stop filling the array at. If end is negative, it is treated as length+end.

index to start filling the array at. If start is negative, it is treated as length+start where length is the length of the array.

value to fill array section with

A function that accepts up to three arguments. The filter method calls the predicate function one time for each element in the array.

An object to which the this keyword can refer in the predicate function. If thisArg is omitted, undefined is used as the this value.

find calls predicate once for each element of the array, in ascending order, until it finds one where predicate returns true. If such an element is found, find immediately returns that element value. Otherwise, find returns undefined.

If provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.

find calls predicate once for each element of the array, in ascending order, until it finds one where predicate returns true. If such an element is found, findIndex immediately returns that element index. Otherwise, findIndex returns -1.

If provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.

A function that accepts up to three arguments. forEach calls the callbackfn function one time for each element in the array.

An object to which the this keyword can refer in the callbackfn function. If thisArg is omitted, undefined is used as the this value.

The position in this array at which to begin searching for searchElement.

The element to search for.

The array index at which to begin the search. If fromIndex is omitted, the search starts at index 0.

The value to locate in the array.

A string used to separate one element of an array from the next in the resulting String. If omitted, the array elements are separated with a comma.

The array index at which to begin the search. If fromIndex is omitted, the search starts at index 0.

The value to locate in the array.

A function that accepts up to three arguments. The map method calls the callbackfn function one time for each element in the array.

An object to which the this keyword can refer in the callbackfn function. If thisArg is omitted, undefined is used as the this value.

A function that accepts up to four arguments. The reduce method calls the callbackfn function one time for each element in the array.

If initialValue is specified, it is used as the initial value to start the accumulation. The first call to the callbackfn function provides this value as an argument instead of an array value.

A function that accepts up to four arguments. The reduce method calls the callbackfn function one time for each element in the array.

If initialValue is specified, it is used as the initial value to start the accumulation. The first call to the callbackfn function provides this value as an argument instead of an array value.

A function that accepts up to four arguments. The reduceRight method calls the callbackfn function one time for each element in the array.

If initialValue is specified, it is used as the initial value to start the accumulation. The first call to the callbackfn function provides this value as an argument instead of an array value.

A function that accepts up to four arguments. The reduceRight method calls the callbackfn function one time for each element in the array.

If initialValue is specified, it is used as the initial value to start the accumulation. The first call to the callbackfn function provides this value as an argument instead of an array value.

A typed or untyped array of values to set.

The index in the current array at which the values are to be written.

The end of the specified portion of the array. This is exclusive of the element at the index 'end'.

The beginning of the specified portion of the array.

A function that accepts up to three arguments. The some method calls the predicate function for each element in the array until the predicate returns a value which is coercible to the Boolean value true, or until the end of the array.

An object to which the this keyword can refer in the predicate function. If thisArg is omitted, undefined is used as the this value.

Function used to determine the order of the elements. It is expected to return a negative value if first argument is less than second argument, zero if they're equal and a positive value otherwise. If omitted, the elements are sorted in ascending, ASCII character order.

[11,2,22,1].sort((a, b) => a - b)

The index of the beginning of the array.

The index of the end of the array.
