Using an object hierarchy in Typescript to create an if statement

Currently, I am attempting to create a logical statement using a hierarchy structure as shown below:

if ((config.elementConfig.curve[0].dataset[0].splitBy = 'my discrete var')) {.....

However, when implementing this statement, I encounter the error "error Unexpected constant condition no-constant-condition" from TypeScript.

What modifications can I make to satisfy TypeScript's requirements?

Answer №1

It appears that your issue may stem from attempting a variable assignment rather than an evaluation. The correct operator to use is ==, not =.

The = symbol is employed for assigning values:

const myValue = "thing";

On the other hand, the == symbol is utilized for evaluations.


The error you're seeing is likely due to the expression not evaluating to a form that the if condition can verify!
if (myValue === "thing") {

Thus, it seems that you intend to have:

if ((config.elementConfig.curve[0].dataset[0].splitBy == 'my descrete var')
