- 有人知道下面代码是在干嘛吗？LongBits.prototype.toNumber = function toNumber(unsigned) {
if (!unsigned && this.hi >>> 31) {
var lo = ~this.lo + 1 >>> 0,
hi = ~this.hi >>> 0;
if (!lo)
hi = hi + 1 >>> 0;
return -(lo + hi * 4294967296);
}
return this.lo + this.hi * 4294967296;
};展开评论点赞 - 下面的条件语句你们能扛得住吗？
if (request.charAt(0) !== '.' ||
(request.length > 1 &&
request.charAt(1) !== '.' &&
request.charAt(1) !== '/' &&
(!isWindows || request.charAt(1) !== '\\'))) {
let paths = modulePaths;
if (parent != null && parent.paths && parent.paths.length) {
paths = parent.paths.concat(paths);
}
debug('looking for %j in %j', request, paths);
return paths.length > 0 ? paths : null;
