loop an object and removing based on condition in react-CodePudding

I am using reactjs have the following data below and I want to loop through the array and remove the two entry.

0: {mailId: '[email protected]', firstName: 'one'}
1: {mailId: '[email protected]', firstName: 'two'}
2: {mailId: '[email protected]', firstName: 'three'}
3: {mailId: '[email protected]', firstName: 'four'}
4: {mailId: '[email protected]', firstName: 'five'}

The below two email I want to check it against array and needs to remove it.

[email protected]
[email protected]

I'm expecting a final array like below

0: {mailId: '[email protected]', firstName: 'one'}
1: {mailId: '[email protected]', firstName: 'two'}
2: {mailId: '[email protected]', firstName: 'four'}

If the mail id is only one we can remove like below, but if mailId is again list/array then how can we remove it, please help me.

arrayfilter.filter((item) => item.mailId !== "[email protected]")

CodePudding user response：

Use filter and check if your blacklist emails are includes the mailId

const arr = [{mailId: '[email protected]', firstName: 'one'},
 {mailId: '[email protected]', firstName: 'two'},
 {mailId: '[email protected]', firstName: 'three'},
 {mailId: '[email protected]', firstName: 'four'},
 {mailId: '[email protected]', firstName: 'five'},]
 
 const blackList = ["[email protected]", "[email protected]"]
 
 
 const result = arr.filter(item => !blackList.includes(item.mailId))
 
 console.log(result)

const data = [
{mailId: '[email protected]', firstName: 'one'},
{mailId: '[email protected]', firstName: 'two'},
{mailId: '[email protected]', firstName: 'three'},
{mailId: '[email protected]', firstName: 'four'},
{mailId: '[email protected]', firstName: 'five'},
]

let newArray = [];
const remove = ['[email protected]', '[email protected]']

data.forEach(ele => {
  if(!remove.includes(ele.mailId)) {
    newArray.push(ele)
  }
})

console.log(newArray)
