for example, I have code like this:
var test = function() {
return Math.random();
}
var randomNumber = test();
// I want to call test() via the randomNumber variable,
// use this variable on another function or etc...
// for example here
for (var i = 0; i < 5; i++) {
console.log(randomNumber); // and it should be show 4 random numbers
}
Is this possible?
Thanks to advance.
I believe you want to assign the function reference to randomNumber instead of calling the function and assigning its return value.
var test = function() {
return Math.random();
}
// Assign test to randomNumber, but don't call it here
var randomNumber = test;
for (var i = 0; i < 5; i++) {
console.log(randomNumber()); // call it here
}You could assign the value returned by the function to the variable inside the loop and then display it.
Kinda like the code below
// define function
var test = function() {
return Math.random();
}
// define variable
var randomNumber;
// loop
for (var i = 0; i < 5; i++) {
// invoke function, assign value to variable
randomNumber = test();
// output it to console.
console.log(randomNumber);
}UPDATE
If you do not want to write code to 'loop' thru your array, you can use a fake array and map the same function to it.
You are not looping thru it yourself but looping thru the array is being performed nonetheless.
// array of fake values
var iterations = [0, 1, 2, 3, 4];
// returns an array of random numbers
console.log(iterations.map(function(elem) {
return Math.random();
}));
randomNumber = test(); console.log(randomNumber);?Object.defineProperty
