How to make a if-else condition in Kotlin using an Integer

I need to compare Objects with a lot of properties in Kotlin to determine if they are equals, and I want to know if I can do it in a non verbose way. (Cast Int -> Boolean) for example.

I have implemented this with When and another conditions but I don’t find how to cast Integer to Boolean in a Kotlin correct way

In Groovy I can make something like this

@Override int compareTo(Message message) {  int equalName = <=> message?.name  return equalName ?: this.type <=> message?.type } 

In Kotlin I have made this, but Integer is not casting to Boolean so I have to put more code to obtain the same result and it get worst with more properties…

override fun compareTo(other: Message): Int {     return if ( != 0) -1         else this.type.compareTo(other.type) } 

My Object is more verbose than that.

Is there a cleaner way to do this, of it’s considered correct the actual implementation.

`void` function to replace if-else with short circuit expression

It’s about the “code in question” in the following code:

const s = "waterrfetawx"; const del = 2; function palindromePossible(str, deleteAtMost) {   const set = new Set();   for (let i = 0, len = str.length; i < len; i++) {     const char = str[i];     void(set.delete(char) || set.add(char)); // <-- code in question   }   return set.size <= deleteAtMost + 1; } 

The code in question can also be written like this:

if (set.has(char)) {   set.delete(char) } else {   set.add(char) } 

I’m not too convinced myself whether void(...) is considered “clean”, i.e. readable, maintainable, and clear because it only wraps an expression into a statement. How would have you written it better?

avoid if-else block in favor of default assignment followed by if

A colleague, and frankly better software engineer that me, is telling me that this pattern

let variable = someDefaultVariable(); if (some_boolean) {     variable = someOtherValue(); } 

is better than this pattern

let variable if (some_boolean) {     variable = someOtherValue(); } else {     variable = someOtherValue(); } 

My doubt about this is that the initial instantiation is going to involved a waterfall of function calls before the if block is hit, although he seems convinced that the first appraoch is better.

Speaking specifically about Javascript, which of these patterns is more better and more secure. Is this the same for C?

is it possible to use if-else statements in mocha’s it() function individually?

I recently started with mocha and wanted to know if we could use if else statements for conditional testing. I want to be able to use conditions in ever it() function in order to put assertions on Json data received in response to that getprojection() function call.

I have posted a code as an example to illustrate what I am trying to achieve. Any help would be appreciated. Thanks!!

var assert = require('chai').assert; var expect = require('chai').expect; var should = require('chai').should(); // var projection = require(''); var projectionsTest = require('./getProjection')        describe("Annual Tax Projection", function () {         describe("Current Year Tax - #2018", function () {             it("should return correct taxable Income", function (done) {                 projectionsTest.getProjection('params', 'params', function (projections) {                     if (grossIncome <= deductions){                         assert.deepEqual(projections[2018].taxableIncome, 0)                     }else throw new Error("There is something wrong with tax calculation")                     done(Error);                 });             });             it("should check federal tax is calculated correctly", function (done) {                 projectionsTest.getProjection('params', 'params', function (projections) {                     if (taxableIncome === 0 || taxBracket ===10){                         assert.deepEqual(projections[2018]. )                     }else                     done(Error);                 });             });         });     })
