About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Methods
Uint32Array.from( src[, map[, thisArg]] )
Creates a new typed array from an array-like object or an iterable.
1var arr = Uint32Array.from( [ 1, 2 ] ); 2// returns <Uint32Array>[ 1, 2 ]
To invoke a function for each src value, provide a callback function.
1function mapFcn( v ) { 2 return v * 2; 3} 4 5var arr = Uint32Array.from( [ 1, 2 ], mapFcn ); 6// returns <Uint32Array>[ 2, 4 ]
A callback function is provided two arguments:
value: source valueindex: source index
To set the callback execution context, provide a thisArg.
1function mapFcn( v ) { 2 this.count += 1; 3 return v * 2; 4} 5 6var ctx = { 7 'count': 0 8}; 9 10var arr = Uint32Array.from( [ 1, 2 ], mapFcn, ctx ); 11// returns <Uint32Array>[ 2, 4 ] 12 13var n = ctx.count; 14// returns 2
Uint32Array.of( element0[, element1[, ...elementN]] )
Creates a new typed array from a variable number of arguments.
1var arr = Uint32Array.of( 1, 2 ); 2// returns <Uint32Array>[ 1, 2 ]
Uint32Array.prototype.copyWithin( target, start[, end] )
Copies a sequence of elements within an array starting at start and ending at end (non-inclusive) to the position starting at target.
1var arr = new Uint32Array( [ 1, 2, 3, 4, 5 ] ); 2 3// Copy the last two elements to the first two elements: 4arr.copyWithin( 0, 3 ); 5 6var v = arr[ 0 ]; 7// returns 4 8 9v = arr[ 1 ]; 10// returns 5
By default, end equals the number of array elements (i.e., one more than the last array index). To limit the sequence length, provide an end argument.
1var arr = new Uint32Array( [ 1, 2, 3, 4, 5 ] ); 2 3// Copy the first two elements to the last two elements: 4arr.copyWithin( 3, 0, 2 ); 5 6var v = arr[ 3 ]; 7// returns 1 8 9v = arr[ 4 ]; 10// returns 2
When a target, start, and/or end index is negative, the respective index is determined relative to the last array element. The following example achieves the same behavior as the previous example:
1var arr = new Uint32Array( [ 1, 2, 3, 4, 5 ] ); 2 3// Copy the first two elements to the last two elements: 4arr.copyWithin( -2, -5, -3 ); 5 6var v = arr[ 3 ]; 7// returns 1 8 9v = arr[ 4 ]; 10// returns 2

When a start and/or end index is negative, the respective index is determined relative to the last array element.
1var arr = new Uint32Array( 2 ); 2 3// Set all array elements, except the last element, to the same value: 4arr.fill( 2, -arr.length, -1 ); 5 6var v = arr[ 0 ]; 7// returns 2 8 9v = arr[ 1 ]; 10// returns 0

The comparison function is provided two array elements, a and b, per invocation, and its return value determines the sort order as follows:
- If the comparison function returns a value less than zero, then the method sorts
ato an index lower thanb(i.e.,ashould come beforeb). - If the comparison function returns a value greater than zero, then the method sorts
ato an index higher thanb(i.e.,bshould come beforea). - If the comparison function returns zero, then the relative order of
aandbshould remain unchanged.
Uint32Array.prototype.subarray( [begin[, end]] )
Creates a new typed array view over the same underlying ArrayBuffer and with the same underlying data type as the host array.
1var arr1 = new Uint32Array( [ 1, 2, 3 ] ); 2 3var arr2 = arr1.subarray(); 4// returns <Uint32Array>[ 1, 2, 3 ] 5 6var bool = ( arr1.buffer === arr2.buffer ); 7// returns true
By default, the method creates a typed array view beginning with the first array element. To specify an alternative array index at which to begin, provide a begin index (inclusive).
1var arr1 = new Uint32Array( [ 1, 2, 3 ] ); 2 3var arr2 = arr1.subarray( 1 ); 4// returns <Uint32Array>[ 2, 3 ] 5 6var bool = ( arr1.buffer === arr2.buffer ); 7// returns true
By default, the method creates a typed array view which includes all array elements after begin. To limit the number of array elements after begin, provide an end index (exclusive).
1var arr1 = new Uint32Array( [ 1, 2, 3 ] ); 2 3var arr2 = arr1.subarray( 0, 2 ); 4// returns <Uint32Array>[ 1, 2 ] 5 6var bool = ( arr1.buffer === arr2.buffer ); 7// returns true
When a begin and/or end index is negative, the respective index is determined relative to the last array element.
1var arr1 = new Uint32Array( [ 1, 2, 3 ] ); 2 3var arr2 = arr1.subarray( -arr1.length, -1 ); 4// returns <Uint32Array>[ 1, 2 ] 5 6var bool = ( arr1.buffer === arr2.buffer ); 7// returns true
If the method is unable to resolve indices to a non-empty array subsequence, the method returns an empty typed array.
1var arr1 = new Uint32Array( [ 1, 2, 3 ] ); 2 3var arr2 = arr1.subarray( 10, -1 ); 4// returns <Uint32Array>[]
Uint32Array.prototype.toLocaleString( [locales[, options]] )
Serializes an array as a locale-specific string.
1var arr = new Uint32Array( [ 1, 2, 3 ] ); 2 3var str = arr.toLocaleString(); 4// returns '1,2,3'
Uint32Array.prototype.toString()
Serializes an array as a string.
1var arr = new Uint32Array( [ 1, 2, 3 ] ); 2 3var str = arr.toString(); 4// returns '1,2,3'
Uint32Array.prototype.values()
Returns an iterator for iterating over array elements.
1var arr = new Uint32Array( [ 1, 2 ] ); 2 3// Create an iterator: 4var it = arr.values(); 5 6// Iterate over array elements... 7var v = it.next().value; 8// returns 1 9 10v = it.next().value; 11// returns 2 12 13var bool = it.next().done; 14// returns true
