Variables

variable traverse

method baseTypeStrictlyMatches

method buildCodeFrameError

buildCodeFrameError: <TError extends Error>(
    msg: string,
    Error?: new (msg: string) => TError
) => TError;

method call

call: (key: string) => boolean;

method canHaveVariableDeclarationOrExpression

canHaveVariableDeclarationOrExpression: () => boolean;

This checks whether or not we're in one of the following positions:
for (KEY in right); for (KEY;;);
This is because these spots allow VariableDeclarations AND normal expressions so we need to tell the path replacement that it's ok to replace this with an expression.

method canSwapBetweenExpressionAndStatement

canSwapBetweenExpressionAndStatement: (replacement: Node) => boolean;

This checks whether we are swapping an arrow function's body between an expression and a block statement (or vice versa).
This is because arrow functions may implicitly return an expression, which is the same as containing a block statement.

method couldBeBaseType

couldBeBaseType: (name: string) => boolean;

method debug

debug: (buildMessage: () => string) => void;

method equals

equals: (key: string, value: any) => boolean;

Check whether the path node key strict equals value.

method evaluate

evaluate: () => { confident: boolean; value: any };

Walk the input node and statically evaluate it.
Returns an object in the form { confident, value }. confident indicates whether or not we had to drop out of evaluating the expression because of hitting an unknown node that we couldn't confidently find the value of.
Example:
t.evaluate(parse("5 + 5")) // { confident: true, value: 10 } t.evaluate(parse("!true")) // { confident: true, value: false } t.evaluate(parse("foo + foo")) // { confident: false, value: undefined }

method evaluateTruthy

evaluateTruthy: () => boolean;

Walk the input node and statically evaluate if it's truthy.
Returning true when we're sure that the expression will evaluate to a truthy value, false if we're sure that it will evaluate to a falsy value and undefined if we aren't sure. Because of this please do not rely on coercion when using this method and check with === if it's false.

method find

find: (callback: (path: NodePath) => boolean) => NodePath | null;

Starting at current NodePath and going up the tree, return the first NodePath that causes the provided callback to return a truthy value, or null if the callback never returns a truthy value.

method findParent

findParent: (callback: (path: NodePath) => boolean) => NodePath | null;

Starting at the parent path of the current NodePath and going up the tree, return the first NodePath that causes the provided callback to return a truthy value, or null if the callback never returns a truthy value.

method get

static get: <C extends Node, K extends keyof C>(opts: {
