How to remove item from array by value? [duplicate]

Answer 1

You can do it with these two ways:

const arr = ['1', '2', '3', '4'] // we wanna delete number "3"

1. The first way:

   arr.indexOf('3') !== -1 && arr.splice(arr.indexOf('3'), 1)
   

2. The second way (ES6) specially without mutate:

   const newArr = arr.filter(e => e !== '3')
