The upper byte of "version made by", indicates the compatibility of the file attribute information.
The comment for this file
The length of the comment

datetimeThe mapping of the external attributes is host-system dependent. For MS-DOS, the low order byte is the MS-DOS directory attribute byte. If input came from standard input, this field is set to zero.
This should be used for storage expansion.
The length of the extra field
General purpose bit flags
This is the offset from the start of the first disk on which this file appears to where the local header should be found.
Whether this entry is a directory
Whether this entry is a file
The date and time are encoded in standard MS-DOS format. This getter decodes the date.
The name of the file, with optional relative path. The filename is preloaded here, since looking it up is expensive.
4.4.17.1 claims:
Unfortunately, this isn't true in practice. Some Windows zip utilities use a backslash here, but the correct Unix-style path in file headers. To avoid seeking all over the file to recover the known-good filenames from file headers, we simply convert '' to '/' here.
The length of the file name
The total size of the this entry
The number of the disk on which this file begins.
The size of the file uncompressed
The minimum supported ZIP specification version needed to extract the file.
The lower byte of "version made by", indicates the ZIP specification version supported by the software used to encode the file.

to end
index to a static value
and returns the modified array
value to fill array section with
Optional
start: numberindex to start filling the array at. If start is negative, it is treated as length+start where length is the length of the array.
Optional
end: numberindex to stop filling the array at. If end is negative, it is treated as length+end.

A function that accepts up to three arguments. The filter method calls the predicate function one time for each element in the array.
Optional
thisArg: anyAn object to which the this keyword can refer in the predicate function. If thisArg is omitted, undefined is used as the this value.
Returns the value of the first element in the array where predicate is true, and undefined otherwise.
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.
Optional
thisArg: anyIf provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.
Returns the index of the first element in the array where predicate is true, and -1 otherwise.
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.
Optional
thisArg: anyIf provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.
Returns the value of the last element in the array where predicate is true, and undefined otherwise.
findLast calls predicate once for each element of the array, in descending order, until it finds one where predicate returns true. If such an element is found, findLast immediately returns that element value. Otherwise, findLast returns undefined.
Optional
thisArg: anyIf provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.
Optional
thisArg: anyReturns the index of the last element in the array where predicate is true, and -1 otherwise.
findLastIndex calls predicate once for each element of the array, in descending order, until it finds one where predicate returns true. If such an element is found, findLastIndex immediately returns that element index. Otherwise, findLastIndex returns -1.
Optional
thisArg: anyIf provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.
Performs the specified action for each element in an array.
A function that accepts up to three arguments. forEach calls the callbackfn function one time for each element in the array.
Optional
thisArg: anyAn object to which the this keyword can refer in the callbackfn function. If thisArg is omitted, undefined is used as the this value.
Determines whether an array includes a certain element, returning true or false as appropriate.
The element to search for.
Optional
fromIndex: numberThe position in this array at which to begin searching for searchElement.
Returns the index of the first occurrence of a value in an array.
The value to locate in the array.
Optional
fromIndex: numberThe array index at which to begin the search. If fromIndex is omitted, the search starts at index 0.
Adds all the elements of an array separated by the specified separator string.
Optional
separator: stringA 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.
Returns the index of the last occurrence of a value in an array.
The value to locate in the array.
Optional
fromIndex: numberThe array index at which to begin the search. If fromIndex is omitted, the search starts at index 0.
