The variable 'stat' is being implicitly assigned the type 'any'. Error code TS7031 is triggered in Typescript

Question

The variable 'stat' is being implicitly assigned the type 'any'. Error code TS7031 is triggered in Typescript

import * as React from 'react'
import { report, valueColor } from './Constant'
import StatCard from './StatCard'

export default function ListOfStat() {
  return (
    <div className="w-11/12 mx-auto mt-10 grid gap-2">
      {report.casese.map((stat, index) => {
        const { label, value, delta } = stat
        return (
          <StatCard stat={stat} key={index} valueColor={valueColor[index]} />
        )
      })}
    </div>
  )
}

Can you give me a hand with this? I'd appreciate it. Thank you in advance. I've tried everything to solve it. The code was taken from the tutorial at this link: https://www.youtube.com/watch?v=nZPrwNK-tz8

The issue I'm facing is described below:

Binding element 'stat' implicitly has an 'any' type.  TS7031

    1 | import React from 'react'

      |                                    ^
    4 |   const { label, value, delta } = stat
    5 |   return (
    6 |     <div className="h-28 w-full bg-grey-200 rounded flex items-center p-5 ">

Answer №1

When working with Typescript files (such as *.ts or *.tsx), it is important to define the types for the arguments of StatCard. On the other hand, if you prefer not to use types, you can simply rename the files to *.js or *.jsx.

To address the issue with types, the proposed solution could look something like the example below (please ensure to verify the correct types):

export default function StatCard({ 
  stat,
  valueColor,
}: { 
  stat: { label: string, value: number, delta: number }
  valueColor: number
}) {
...
}
