                  {v:'5',l:'label5'}]
const filter1 = arrList.filter((a) => a.l !== 'label1')

Or you can use a much simpler solution:

arrList.filter((a) => !['label1', 'label3'].includes(a.l))

You are using 2 statement to filter, first not equal to label1 and another statement label3. You can combine them in a single statement with AND && operator, as follow

const filter1 = arrList.filter((a) => a.l !== 'label1' && a.l !== 'label3')

You can use && to combine logical statements in to a single filter() expression:

const arrList = [{v:'1',l:'label1'},{v:'2',l:'label2'},{v:'3',l:'label3'}, {v:'4',l:'label4'},{v:'5',l:'label5'}]
const filtered = arrList.filter(a => a.l !== 'label1' && a.l !== 'label3')
console.log(filtered);

Try something like this!

 const arrList = [{v:'1',l:'label1'},{v:'2',l:'label2'}, 
                  {v:'3',l:'label3'}, {v:'4',l:'label4'}, 
                  {v:'5',l:'label5'}]
const filter1 = arrList.filter((a) => a.l !== 'label1' && a.l !== 'label3')
console.log(filter1);

const filter3 = arrList.filter((a) => a.l !== 'label1' && a.l !== 'label3')

You could filter it like this.

const myFilter = arrList.filter(label => label.l !== 'label1' && label.l !== 'label3');
