random-all

Generates random numbers, unique random numbers

  const random = require('random-all')
  
  let uniqueValue = random.getUnique(1,10);
  let randomInt = random.getInt(1,10);
  let randomFloat = random.getFloat(1,10);

Installation

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

  npm install --save random-all

Usage

  const random = require('random-all')

getUnique(min,max) : Returns a unique random number from (including) min to (including) max.
After all unique value between min and max it will restart cycle.
- min : minimum value of random number. Defaults to 1.
- max : maximum value of random number. Defaults to 100.
```
  const random = require('random-all')

  let val = random.getUnique(1,10);// unique val is between 1 and 10.
  let val = random.getUnique()// unique val is between 1 and 100.
```
getInt(min,max) : Returns a random number from (including) min to (including) max.
- min : minimum value of random number. Defaults to 1.
- max : maximum value of random number. Defaults to 100.
```
  const random = require('random-all')

  let val = random.getInt(1,10);// val is between 1 and 10.
  let val = random.getInt()// val is between 1 and 100.
```

getFloat(min,max) : Returns a random number from (including) min to (including) max.

min : minimum value of random number. Defaults to 1.

max : maximum value of random number. Defaults to 100.

  const random = require('random-all')

  let val = random.getFloat(1,10);// val is between 1 and 11.
  let val = random.getFloat(0,0);// val is between 0 and 1.
  let val = random.getFloat(1,1);// val is between 1 and 2.
  let val = random.getFloat()// val is between 1 and 101.

getChar(str,isUnique) : Returns a random char from string given.

str : string value from which a random char to be fetched. Defaults to "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".

isUnique : Return unique char.

  const random = require('random-all')

  let val = random.getChar();// val will be a char from "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
  let val = random.getChar("abc");// val will be a or b or c.

  //Calling in a loop without unique
  for(let i = 0;i<4;i++){
    console.log(random.getChar("abc"));
  } //output can be a,b,a,a;

  //Calling in a loop with unique
  for(let i = 0;i<4;i++){
    console.log(random.getChar("abc",true));
  } //output can be b,a,c,a;

getBoolean(percent) : Returns a random boolean value.

percent : this percent of times true will be returned. Defaults to 50

  const random = require('random-all')

  let val = random.getBoolean(); Probabilty of true and false is 50
  let val = random.getBoolean(30); Probabilty of true and false is 30 and 70 repectively.

choices(population,weights) : Return a random element from the non-empty sequence according to there weight.
- population : elements from which an element should be choosen.
- weights : weights of each element, the sum should be equal to 100.
```
  const random = require('random-all')

  let val = random.choices(["a","b","c"],[10,40,60]);// val will be a or b or c, occurence would be based on there weights
```
setChoices(population,weights) : Used to set the elements and there weigts, later used by choices(). This is recommeded over passing parameters directly to choices()
- population : elements from which an element should be choosen.
- weights : weights of each element, the sum should be equal to 100.
```
  const random = require('random-all')
  random.setChoices(["a","b","c"],[10,40,60]);
  let val = random.choices();// val will be a or b or c, occurence would be based on there weights.
```

Usage no npm install needed!
