示例1: it
it('should support function expressions', () => {
expect(emitStmt(o.fn([], []).toStmt())).toEqual(['():void => {', '};'].join('\n'));
expect(emitStmt(o.fn([], [new o.ReturnStatement(o.literal(1))], o.INT_TYPE).toStmt()))
.toEqual(['():number => {', ' return 1;\n};'].join('\n'));
expect(emitStmt(o.fn([new o.FnParam('param1', o.INT_TYPE)], []).toStmt()))
.toEqual(['(param1:number):void => {', '};'].join('\n'));
});示例2: it
it('should support function expressions', () => {
expect(emitStmt(o.fn([], []).toStmt())).toEqual(['function() {', '};'].join('\n'));
expect(emitStmt(o.fn([], [new o.ReturnStatement(o.literal(1))]).toStmt()))
.toEqual(['function() {', ' return 1;\n};'].join('\n'));
expect(emitStmt(o.fn([new o.FnParam('param1')], []).toStmt()))
.toEqual(['function(param1) {', '};'].join('\n'));
});示例3: it
it('should support function expressions', () => {
expect(emitStmt(o.fn([], []).toStmt())).toEqual(['() {', '};'].join('\n'));

});示例4: createOperatorFn
function createOperatorFn(op: o.BinaryOperator) {
return o.fn(
[new o.FnParam('a'), new o.FnParam('b')],
[new o.ReturnStatement(new o.BinaryOperatorExpr(op, o.variable('a'), o.variable('b')))],
o.DYNAMIC_TYPE);
}示例5:
o.variable('map')
.set(o.literalMap([
['someKey', o.literal('someValue')],
['changeable', o.literal('initialValue')],
]))
.toDeclStmt(),
o.variable('map').key(o.literal('changeable')).set(o.literal('changedValue')).toStmt(),

.set(o.importExpr(testDataIdentifier).instantiate([o.literal('someValue')]))
.toDeclStmt(),

o.variable('fn')
.set(o.fn([new o.FnParam('param')],
