First off, you need to fix the objects' initialization. Object's property assignment uses a colon ':' not an assignment operator '=' Example: { ato : "anything", num : 42 } To find index of an array element we can use findIndex() method console.log( array.findIndex( element => element.num == 3 ) ); Reference: https://developer.mozilla.org/id/docs/Web/JavaScript/Reference/Global_Objects/Array/findIndex

Use findIndex method const array = [ {ato:"anything1",num:11}, {ato:"anything2",num:3}, {ato:"anything3",num:7} ] const index = array.findIndex(arr => arr.num===3) console.log(index)
