javascript - How to make if and else execute and output console.log() at the same time

Question

if(条件){
        console.log('ab')
    }else{
        console.log('cd')
    }
    
    条件这里可以添加任意代码
    最终结果是console.log('abcd')
    办法貌似有很多，但是好像很多人想到的是不能同时成立

Answer 1

if (条件) {
    console.log('ab')
} else {
    console.log('cd')
}

You can add any code here for the conditions
The final result is console.log('abcd')
There seem to be many ways, but it seems that many people think that it cannot be established at the same time

Isn’t this a question from @南小鸟’s blog last time I read it? .

01 Replacement

if (console.log('abcd'), console.log = () => {}){
    console.log('ab');
} else {
    console.log('cd'); 
}

02 Replacement

if (console._log = console.log, console.log = str => console._log(str + 'cd')){
    console.log('ab');
} else {
    console.log('cd'); 
}

03 bind

if (!( console.log = console.log.bind(console, 'ab'))){
    console.log('ab');
} else {
    console.log('cd'); 
}

But the result is that 'ab cd' has an extra space...

04 setTimeout + replacement

if (setTimeout(console.log.bind(null, 'abcd')), console.log = _ => _) {
    console.log('ab')
} else {
    console.log('cd')
}

05 setTimeout + clear screen

if (setTimeout(_ => { console.clear(), console.log('abcd') })){
    console.log('ab')
} else {
    console.log('cd')
}

Answer 2

. . . . . . . Is it because I don’t understand your needs or you lack basic programming logic
if else is mutually exclusive

Answer 3

ab abcd || cd abcd logically does not exist at the same time

Answer 4

if(condition){
console.log('ab');
}

if (another condition) {
console.log('cd');
}

if and else can only run one of the conditions. If the if condition is met, else will not be run

Answer 5

if(true){}else if(false){
   console.log('ab')
}else{
   console.log('cd')
}
console.log('abcd')

It’s just mind-boggling. .

Answer 6

if(console.log('ab')){
    console.log('ab'))
}else{
    console.log('cd')
}

Answer 7

I have a problem in my head. Which one should be written in the production environment and tried and executed at the same time? .

Answer 8

Looking at the adopted answers, the first question is about simultaneous execution. They are all about saving the country through curves just to output abcd. Where can I see that they are executed at the same time?
