1. Base Conversion Between Bases 2-36Write a JavaScript function to convert a number from one base to another.Note : Both bases must be between 2 and 36.Test Data :console.log(base_convert('E164',16,8));console.log(base_convert(1000,2,8));...
Then it is added to the smaller number to produce a random number between the given range. Example 3: Generate random integer between two numbers // Generating random integer in range [x, y)// The maximum is exclusive and the minimum is inclusive ...
Generate a Random Number Between Two Numbers in JavaScript If we also want to have a user-defined minimum value, we need to change the equation ofMath.random() * maxtoMath.random() * (max-min)) +min. Using this equation the returned value is a random number betweenminandmax. ...

Let's say we're going for a random number between 0 and 4. Because Math.random gives us a random number between 0 and 1, this is a relatively straightforward problem: we can multiply the result by 4, and round down to get the integer:...
