how to check array contains value

Issue

I need to check "Drinks" is already exist in this array if it exists I need to replace the new value instead of the "Drinks:Focus"

["Drinks:Focus", "Baked:No", "Addons:320"]

my angular version

@angular-devkit/architect         0.803.19 (cli-only)
@angular-devkit/build-optimizer   0.0.35
@angular-devkit/core              8.3.19 (cli-only)
@angular-devkit/schematics        8.3.19 (cli-only)
@schematics/angular               8.3.19 (cli-only)
@schematics/update                0.803.19 (cli-only)
rxjs                              5.5.6
typescript                        2.4.2
webpack                           3.12.0

Solution

You can use Array.map() and String.includes() to achieve this, as followings:

let arr = ["Drinks:Focus", "Baked:No", "Addons:320"]

arr = arr.map(item => item.includes('Drinks') ? item.replace('Drinks','Beverage') : item)

console.log(arr)
