Prevent the use of a single equals sign in an if statement

When it comes to assigning values conditionally in JavaScript, it's important to use a linter like TSLint rather than relying on the Typescript compiler. Check out TSLint for this purpose. The specific rule you're interested in is known as no-conditional-assignment.

To implement this rule, add it to your tslint.json file:

{
  "rules": [
    "no-conditional-assignment": true
  ]
}
