var len = MAX_TYPED_ARRAY_LENGTH;
// returns 9007199254740991

Examples

var ctors = require( '@stdlib/array-ctors' );
var MAX_TYPED_ARRAY_LENGTH = require( '@stdlib/constants-array-max-typed-array-length' );

function fill( dtype, len, value ) {
    var ctor;
    var arr;
    var i;
    if ( len > MAX_TYPED_ARRAY_LENGTH ) {
        throw new RangeError( 'invalid argument. The maximum length for a typed array is '+MAX_TYPED_ARRAY_LENGTH+'.' );
    }
    ctor = ctors( dtype );
    arr = new ctor( len );
    for ( i = 0; i < len; i++ ) {
        arr[ i ] = value;
    }
    return arr;
}

var arr = fill( 'float64', 10, 3.14 );
console.log( arr );

try {
