由于JavaScript的函数也是一个对象,上述定义的abs()函数实际上是一个函数对象,而函数名abs可以视为指向该函数的变量。故第二种定义是 //在这种方式下,function (x) { ... }是一个匿名函数,它没有函数名。但是,这个匿名函数赋值给了变量abs,所以,通过变量abs就可以调用该函数。 var abs = function (x) { ...
The JavaScript abs() function return the absolute value or modulus |x| of a real number x is the non-negative value of x without regard to its sign.

Q: How does the abs function work in programming? A: Theabsfunction in programming works by taking an input number as its argument and returning its positive magnitude. If the input number is positive or zero, the function simply returns the number itself. However, if the input number is ...
