I have a scenario where I have "Promise A" and "Promise B". I need to call both promises only if the variable "value" is false, else, I only need to call the Promise B.
So, I wrote this code:
if(!value){
PromiseA.then((newValue)=>{
PromiseB.then((newValue)=>{
//...
})
})
}
else{
PromiseB.then((value)=>{
//....
})
}
This code works fine, but I'm wondering if there is a better way to accomplish this than using "if-else".
This for have clean code.
Thanks in advance.
Inside an async function, await the first Promise if you need to.
const firstValue = value ?? await PromiseA;
const resultOfPromiseB = await PromiseB;
// do stuff with resultOfPromiseB
You can wrap the second promise in a function if you want to avoid code repetition.
function callPromiseB() {
PromiseB.then((value)=>{
//....
})
}
if(!value){
PromiseA.then((newValue)=>{
callPromiseB()
})
}
else{
callPromiseB()
}
