1、arrayAverage 返回数字数组的平均值。 使用Array.reduce()将每个值添加到累加器中, 并以0的值初始化, 除以数组的length。 const arrayAverage = arr => arr.reduce((acc, val) => acc + val, 0) / arr.length; // arrayAverage([1,2,3]) -> 2 2、arraySum 返回一个数字数组的总和。 使用Arra...
("age is {}",age);// constants (must be uppercase and explicit type definition)constBRAND:&str="Dell";println!("brand is {}",BRAND);// multiple assignment (tuple destructuring)// more on tuples later in the articlelet(status,code)=("OK",200);println!("status: {}, code: {}",...
function average() { return (() => { const length = arguments.length; if (length == 0) return 0; const numbers = Array.prototype.slice.call(arguments); const sumReduceFn = function (a, b) { return a + Number(b) }; return numbers.reduce(sumReduceFn, 0) / length; })(); } ...
Average: $115,930 High: $184,207 As for Chicago Node.JS developer salary, ZipRecruiter came up with the following numbers: Low: $22,663 Average: $121,082 High: $178,730 Therefore, the salaries in our research and those provided by ZipRecruiter are slightly different. This proves that va...
.wordCount()- count the # of terms in the document .confidence()- an average score for pos tag interpretations Match (match methods use thematch-syntax.) .match('')- return a new Doc, with this one as a parent .not('')- return all results except for this ...
GC in V8 employs stop-the-world strategy, therefore it means more objects you have in memory the longer it will take to collect garbage. On log below you can clearly see that in the beginning of the application life it would take an average of 20ms to collect the garbage, but few hund...

avgThe average calculated by avg is the arithmetic mean (the sum of the values divided by the number of values).// Average - is a term mid of the all given data point. console.log(solverjs.avg([5, 6, 8, 9, 3])); // The output is : 6.2 ...

It's much more safety when you assume that ids are random. And stop to use this function.// If you need to access all worksheets in a loop please look to the next example.constworksheet=workbook.getWorksheet(1);// access by `worksheets` array:workbook.worksheets[0];//the first one; ...
