TS1100

Invalid use of '{0}' in strict mode.

`eval` or `arguments` is used as a name in strict-mode code. Rename the variable, parameter or function.

What it means

In strict mode, eval and arguments can't be declared or assigned: not as a variable, function, parameter or catch binding. This code is reported in scripts with a "use strict" directive. Modules and classes are always strict, and report the same mistake as TS1215 and TS1210.

Example

index.ts
"use strict";
var arguments = 1;
ts-r-check -p tsconfig.json --pretty false ts-r output
index.ts(2,5): error TS1100: Invalid use of 'arguments' in strict mode.

Recorded by node scripts/verify-examples.mjs with ts-r built from commit 6deaf01. The example uses the default tsconfig: strict, target: es2022, module: esnext, moduleResolution: bundler.

How to fix

  • Rename the binding, for example args or evaluate.
  • To read all arguments of a function, use a rest parameter: function f(...args: unknown[]).
