remove array component from object

Question

I have some compllex component which contains array

this.SomeComponent.subArray

SomeComponent:model1;

model1 definition:

someString1:string;
someString2:string;
someString3:string;
subArray[]

model2 definition:

someString22:string;
someString23:string;
someString24:string;

Now if I console.log(JSON.stringify(this.SomeComponent.subArray)); I get :

SomeComponent[{"someString22":"one","someString23":"yellow","someString24":"water",},
{"someString22":"two","someString23":"red","someString24":"ground",}
{"someString22":"three","someString23":"green","someString24":"air",}]

Now my task is to delete subArray part which has someString23==red. So When I console log next time I must get only this

SomeComponent[
    {"someString22":"two","someString23":"red","someString24":"ground",}
    {"someString22":"three","someString23":"green","someString24":"air",}]

How can I do that?

question solved, thanks to Aakash Garg and Michael D. You guys rock! :) — David

Use filter method like below :-

this.subArray = subArray.filter((item) => item["someString23"]!==red);

Hi Akash Garg, I've update question. I want to actually delete that part so after new console.log it must not be displayed
