TypeScript function encountering issues with proper evaluation of set iteration

Whenever I attempt to run the code below, I consistently receive this console message: "undefined is not an object (evaluating 'this.courseAvailThisTerm')". Even though the courseAvailThisTerm() function functions properly in other scenarios. Any ideas on why this error persists? I've attempted altering the version of the for loop, but that hasn't resolved the issue.

for(let quarter of degreePlan) {
    foundationCourseSet.forEach(function(fc) {
            if(this.courseAvailThisTerm(fc, quarter.term))
                console.log("It was avail!");
        });
}
angulartypescriptset

Answer №1

Check out this solution:

for(let term of studentSchedule) {
    availableCourses.forEach((course) => {
            if(this.courseAvailableForTerm(course, term))
                console.log("Course is available for enrollment!");
        });
}

I updated the code from using function (fc) {..} to arrow function syntax (fc) => {...}, maintaining the correct context of 'this' during function execution.
