stop performing map function on state if certain condition for one time is met

Question

this.state = { glasses :[{id:0,,value:100, show:true,},
                            {id:1,,value:150, show:false},
                            {id:2, value:200, show:true,},
                            {id:3, value:300, show:false,} .  ]
}

I have this data in states. I need to iterate this state through map and If i encounter show:true, it should stop iteration. like it breaks out of map function. Any help would be appreciated.

if you want to break out of iteration you should use a for-loop or forEach for that, not map. — Michael, Mar 20 '20 at 13:13

Why don't you use a for-loop instead?

I am suggesting it because seems it isn't possible to use break on map. A similar question was ask here: Break statement in javascript array map method

Hi, welcome to Stack Overflow. The right thing to do when somebody's question is answered in a different Q&A is vote to close as a duplicate - you'll be able to do this once you have some reputation, in the meantime it's best not to use the "answer" feature as a substitute. – kaya3 Mar 20 '20 at 12:50
I tried this link but not been able to change that particular show to false – Dibakar Jayjot Mar 20 '20 at 12:51
Could you explain it better? @DibakarJayjot – TheMaysk Mar 20 '20 at 12:54
tried using "for loop" and if "show" is "true" then change it to "false" only once @TheMaysk – Dibakar Jayjot Mar 20 '20 at 12:58
Are you using React? If so, maybe this issue is related to React and its state manipulation. – TheMaysk Mar 20 '20 at 13:02
Are you using _this.setState_ to set the new state? – TheMaysk Mar 20 '20 at 13:07
Yes, I am using this.setState – Dibakar Jayjot Mar 20 '20 at 13:08
So, try to open another question tagged as react or add more information to the current one. This may help everyone to solve this issue. – TheMaysk Mar 20 '20 at 13:11
