JavaScript’s numbers are usually entered as decimal floating-point numbers, but they are internally represented as binary floating-point numbers.That leads to imprecision. To understand why, let’s forget JavaScript’s internal storage format and take a general look at what fractions can be well ...

我们前两次调用 multiply 函数且不传递值,那么每一次 x 的默认值都为 {number:10} ,因此打印出该数字的乘积值为20。 第三次调用 multiply 时,我们传递了一个参数,即对象value。 *=运算符实际上是x.number = x.number * 2的简写,我们修改了x.number的值,并打印出值20。 第四次,我们再次传递value对象。
Imagine you have a function multiply(), which takes two arguments, x and y, and you notice that you often call the function to multiply by specific numbers. You could create a generic function that will fix one parameter: var multiply = function multiply(x, y) { return x * y; }, ...
第三次调用 multiply 时,我们传递了一个参数,即对象value。*=运算符实际上是x.number = x.number * 2的简写,我们修改了x.number的值,并打印出值20。 第四次,我们再次传递value对象。x.number之前被修改为20,所以x.number * = 2打印为40。 65. 输出什么? [1, 2, 3, 4].reduce((x, y) => conso...
Many currencies tend to be expressed with decimal quantities. Although it’s possible to represent money as integer “cents” (multiply all quantities by 100), this approach runs into a couple of issues: There’s a persistent mismatch between the way humans think about money and the way it’...
123 + 456 adds the numbers together/ ‘123’ + ‘456’ glues the strings one after the other. Strings are sequences of letters.Variables - buckets of fun Imagine for a moment your program is a bit like a kid on a beach making a sandcastle. The kid is going to need lots of raw ...
